[WILL GIVE BRAINLIEST ANSWER] f(x)=(x-5)(5x+2) write the smaller solution first and the smaller solutuon second
Answers
Answer:
x = - [tex]\frac{2}{5}[/tex], x = 5
Step-by-step explanation:
Given
f(x) = (x - 5)(5x + 2)
To obtain the solutions set f(x) = 0, that is
(x - 5)(5x + 2) = 0
Equate each factor to zero and solve for x
x - 5 = 0 ⇒ x = 5 ← larger x
5x + 2 = 0 ⇒ 5x = - 2 ⇒ x = - [tex]\frac{2}{5}[/tex] ← smaller x

x-3 ; 2x^2-4x+30
Answers
Answer:
not a factor
Step-by-step explanation:
If (x - 3) is a factor then f(3) = 0
f(x) = 2x² - 4x + 30
f(3) = 2(3)² - 4(3) + 30 = 18 - 12 + 30 = 36 ≠ 0
Since f(3) ≠ 0 then (x - 3) is not a factor of f(x)

A(n) ____ is NOT an example of an agreement.
A) Lease
B) Month-to-month
C) Annual
D) Fine Print
Answers
Answer:
D) Fine Print
Fine print is part of an agreement but technically isnt one.
Final answer:
The correct answer is D) Fine Print. Fine Print is not an agreement but refers to the small, often hard-to-read text in a contract that contains important legal provisions.
Explanation:
The correct answer is D) Fine Print. A lease is a contractual agreement between a lessor and a lessee that gives the lessee the right to use a property owned by the lessor for a specific period in exchange for payment. A month-to-month agreement is a type of lease which automatically renews each month until either party decides to terminate it. An annual agreement typically refers to a contract or lease that is renewed once per year.
Chris spent $8 on lunch. 75% was spent on a sub ad the rest was used to buy two cookies. How much was each cookie?
Answers
Answer:
1 dollar.
Step-by-step explanation:
"Chris spent $8 on lunch. 75% was spent on a sub ad the rest was used to buy two cookies. How much was each cookie?"
.75=75%
8*.75=cost of sub=6
total cost- cost of sub=cost of cookies
8-6=2
The cost of 2 cookies is 2 dollars
Now to find the cost per cookie we take the total cost of the cookies, and divide it by the amount of cookies-
2/2=cost per cookie=1
It cost $1 for each cookie.

Answer:
Final answer is m∠D = 61°.
Step-by-step explanation:
Given that m∠C = 98°,
m∠B = 140°,
m∠A = m∠D ,
Using those information we need to find the value of m∠D.
We know that sum of all 4 interior angles of a quadrilateral is always 360°.
So we can write equation:
m∠A +m∠B +m∠C +m∠D = 360°
m∠A + 140° + 98° +m∠D = 360°
m∠D + 140° + 98° +m∠D = 360°
2(m∠D) + 140° + 98° = 360°
2(m∠D) + 238° = 360°
2(m∠D) = 360° - 238°
2(m∠D) = 122°
m∠D = 122°/2
m∠D = 61°
Hene final answer is m∠D = 61°.
Answer:
the answer is 61°
Step-by-step explanation:
360- 98- 140 = 122 ÷2 = 61

The area of a playground is 160 yd2. The width of the playground is 6 yd longer than its length. Find the length and width of the playground.
Answers
Answer:
length=10\ yd, width=16\ yd
Answer:
Length of the playground is 10 yd and the Width of the playground is 16 yd .
Step-by-step explanation:
Formula
Area of a rectangle = Length × Width
As given
The area of a playground is 160 yd².
The width of the playground is 6 yd longer than its length.
Let us assume that the length be x .
Thus
Width = x + 6
Put all the values in the formula
160 = x × (x + 6)
160 = x² + 6x
x² + 6x - 160 = 0
x² + 16x - 10x - 160 = 0
x (x + 16)-10 (x + 16) = 0
(x -10)(x + 16) = 0
Thus
Either (x - 10) = 0 or (x + 16 ) = 0
x = 10 or x = -16
(Negative value is neglected because sides cannot be negative.)
Thus
x = 10
Length = 10 yd
Width = 10 + 6
= 16 yd
Therefore the length of the playground is 10 yd and the width of the playground is 16 yd .

Mary and Jane are trying to set up their marmalade selling business. They started off by peeling the oranges. Mary peels 8 oranges in 10 minutes while Jane peels 3 oranges in 5 minutes. If they need to peel 500 oranges for their first batch of marmalade, how long (in hours) will it take them to finish peeling? (round off to nearest hr)
Answers
Answer:
6.0 hours
Step-by-step explanation:
1 hour is the same as 60 minutes.
"Mary peels 8 oranges in 10 minutes"
1 hour = 60 minutes = 6 * 10 minutes
In 1 hour, she peels 6 times as many oranges, so Mary peels 48 oranges in 1 hour.
"Jane peels 3 oranges in 5 minutes"
1 hour = 60 minutes = 12 * 5 minutes
In 1 hour, she peels 12 times as many oranges, so Jane peels 36 oranges in 1 hour.
Combined, the peel 48 + 36 = 84 oranges in 1 hour.
(500 oranges)/(84 oranges/hour) = 5.952 hours
Answer: 6.0 hours
The perimeter of the triangle below is 4x + 3y. Find the measure of the missing side. (Picture of triangle)
Answers
Answer: 2x+3y
Step-by-step explanation: look at picture
To find the missing side in a triangle with a given perimeter, subtract the lengths of the known sides from the total frame. This is based on the sum of the lengths of all sides of a triangle, which equals its circumference.
Explanation:We need to understand a simple rule about triangles to find the missing side of a triangle where the perimeter is 4x + 3y. The sum of all sides of a triangle equals its edge. So, if we know the length of the other two sides, we can subtract their sum from the total circumference to find the size of the missing side.
For example, if we know that the other two sides of the triangle are 2x and y, respectively, the missing side would be calculated by subtracting the sum of these sides from the given perimeter.
4x + 3y = perimeter
2x + y = known sides
missing side = (4x + 3y) - (2x + y)
Note: This method assumes that x and y values are provided. If they're unknown, we will require additional equations to solve for x and y before calculating the length of the missing side.

Answers
Answer:

Step-by-step explanation:
Area of the big rectangle
= (x + 10)(2x + 5)
= 2x² + 5x + 20x + 50
= 2x² + 25x + 50
Area of the small white rectangle
= (x + 1)(x + 1)
= x² + x + x + 1
= x² + 2x + 1
Area of the shaded area
= (2x² + 25x + 50) - (x² + 2x + 1)
= 2x² + 25x + 50 - x² - 2x - 1
= x² + 23x + 49

Answers
Answer:
4x+2y-5=0
Step-by-step explanation:
since you have to put the problem in that order you take 5 from both sides
Answer:
The correct answer is y = -2x + 5/2
Step-by-step explanation:
y = mx + b. is the y intercept form of a line.
To find the y = mx + b. form
It is given that,
4x + 2y = 5
2y = -4x + 5
Dividing both sides by 2 we get,
2y/2 = (-4x + 5)/2
y = -4x/2 + 5/2
y = -2x + 5/2
Here m = -2 and b = 5/2

When point A( 3, 1) is translated 2 units to the right and 6 units up the coordinates of point A'
Answers
Answer:
A' = (5,7)
Step-by-step explanation:
So, we start with the original point A at (3,1), that means x = 3 and y = 1.
We move it 2 units to the right... so we're moving along the X-axis... and we're moving to the right.. so we're increasing the value of x. That means starting with x = 3, we go 2 more units... we then get to x = 5.
In the same way, we move 6 units up... so we move along the Y-axis. We go up, so we also increase the value of y. Starting with y = 1, we move up by 6 units... so we are now at y = 7.
A' point is then at (5,7).

Answers
Answer:
Step-by-step explanation:
we are given the angles of XYR = 40, ZXY = 130, and SRY = 40 degrees.
angle ZXY is half of angle ZAY, so angle ZXY is 65 degrees.
imagine a line XA (not on the diagram). then ZXA is 32.5 degrees since it is half of YXZ. Angle XZA and ZXA are equal, so XZA is 32.5 degrees. RZA = XZA + RZX = 32.5 + 40 degrees (assuming the upper left stated degree belongs to angle XZA), or simply RZA is 72.5 degrees.
since ZRA = RZA, then ZRA is 72.5 degrees. since angle ZRS = SRY + ZRA, finally ZRA = 40 + 72.5 degrees or simply, ZRS = 112.5 degrees. which visually is blantantly wrong as it appears to be less than 90 degrees.
