Which possibly forms a triangle

Answer:

The first step would be to add 3 on both sides of the equation.

Step-by-step explanation:

Given a polynomial or a quadratic equation, the first step in completing the square is to take the constant term to the other side of the equation. In the polynomial given the constant term is -3 which implies that we can add 3 on both sides of the equation in order to eliminate this constant term from the left hand side;

x^2 -x -3 +3 = 0 + 3

x^2 - x = 3

Answer:

The first step of Bao yu is to isolate the constant

Step-by-step explanation:

For using completing the square to solve the polynomial equation, the equation should be of the type [tex]a^2 \pm 2ab +b^2[/tex] that can also be written as:[tex](a\pm b)^2[/tex]

so, for the given equation: [tex]x^2 -x -3 =0[/tex]

The first step should be to isolate the constant:

[tex]x^2 -x = 3[/tex]

Then we have to make the middle term according to 2ab where a = 1x and b= (1/2) i.e, -2(1x)(1/2) = 1x

so,by adding (1/2)^2 on both sides of equation, we can complete the formula:

[tex]x^2 -x = 3[/tex]

[tex]x^2 -2(x)(\frac{1}{2}) + (\frac{1}{2})^2 = 3 (\frac{1}{2})^2[/tex]

Solving we get,

[tex](x- (\frac{1}{2}))^2 = 13/4[/tex]

So, the first step is to isolate the constant.

Answer:

5x + 6 : 2x² + 12x

Step-by-step explanation:

Width = 4x

Length = x + 6

Perimeter

= 2(4x + x + 6)

= 2(5x + 6)

Area

= 4x(x + 6)

Ratio of perimeter to area:

= 2(5x + 6) : 4x(x + 6)

= (5x + 6) : 2x(x + 6)

= 5x + 6 : 2x² + 12x

Answer:

(5x + 6) : (2x² + 12x)

Step-by-step explanation:

Perimeter = 2(length + width)

= 2[4x + x + 6]

= 2(5x + 6)

Area = length × width

4x × (x + 6)

4x(x + 6)

Perimeter : Area

2(5x + 6) : 4x(x + 6)

(5x + 6) : (2x² + 12x)

Answer:

5 weeks

Step-by-step explanation:

So if the plant is 13 inches tall in the beginning every week adds 2 inches.

0 weeks = 13 inch

1st week = 15 inch

2nd week = 17 inch

3rd week = 19 inch

4th week = 21 inch

5th week = 23 inch

So it would take 5 weeks to grow 23 inches

Answer:

5 weeks for the plant to be 23 inches long

Step-by-step explanation:

You could take the size the plant is supposed to be, which is 23 inches long then subtract how tall the plant is which is 13 inches long then divide by 2 because the plant grows 2 inches each week. Or you could use a chart to help you, until you get to 23 inches. please give me the brainliest answer?

1weeks= 13 inches + 2 inches = 15 inches

2weeks= 15 inches + 2 inches = 17 inches

3weeks= 17 inches + 2 inches = 19 inches

4weeks= 19 inches + 2 inches = 21 inches

5weeks= 21 inches + 2 inches = 23 inches

Answer:

Option A is correct.

Step-by-step explanation:

The credit limit is $6000

New balance after the transactions = $ 3604.50

Available credit on Nikki's card = credit limit - New balance after the transactions

Available credit on Nikki's card = $6000 - $ 3604.50

Available credit on Nikki's card = $ 2395.50

So, Option A is correct.

Answer:

$ 1.23

Step-by-step explanation:

We are given that Jenna bought 6 pounds of apples for $7.38 and we are to find the unit price per pound of apples.

To find that out, we will simply divide the total price of apples by the number of pounds she bought.

Unit price per pound of apples = [tex] \frac { 7 . 3 8 } { 6 } [/tex] = $1.23

Expression: 45+(5 x w)

Hope this helps man.

The expression for the number of dollars in Michael's savings account after w week's will be;

⇒ y = $5w + $45

Where, y is total amount and w is number of weeks.

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

Given that;

Michael starts with $45 in his savings account and adds $5 to the account each week .

Now,

Since, Michael starts with $45 in his savings account and adds $5 to the account each week .

Hence, After w weeks the total amount (y) is,

⇒ y = $45 + $5w

Thus, The expression for the number of dollars in Michael's savings account after w week's will be;

⇒ y = $5w + $45

When the input is -1, the output is 3

The answer is 3

In the given graph, the value of y at x = - 1 is 7.

This means that when the input x is - 1, the corresponding output y is 7. The graph visually represents the relationship between x and y, where each point on the graph corresponds to a specific x - y pair. When x takes the value - 1, the graph intersects the y-axis at the point (- 1, 7), indicating that the output y is 7.

In summary, for x = - 1, the associated output value y is 7, as shown by the graph's plotted point.

To prove two triangles are similar using SSS Similarity Criterion we need to prove that sides of triangles are Proportional.

Sides of two triangles can be obtained using Distance formula.

Coordinates of ΔFGH are=F(-3,-2),G(-1,-3) and H(-4, -3)

Answer:

(C) [tex]110^{\circ}[/tex].

Step-by-step explanation:

Angles formed by drawing lines from the ends of the diameter of a circle to its circumference form a right angle, therefore

[tex]{\angle}FED=90^{\circ}[/tex].

Now, it is given from the figure that [tex]{\angle}FEP=35^{\circ}[/tex], therefore

[tex]{\angle}FED={\angle}FEP+{\angle}DEP[/tex]

[tex]90^{\circ}=35^{\circ}+{\angle}DEP[/tex]

[tex]{\angle}DEP=55^{\circ}[/tex]

Now, we know that The angle subtended at the center of a circle is double the size of the angle subtended at the edge from the same two points, therefore

[tex]{\angle}PCD=2{\angle}PED[/tex]

[tex]{\angle}PCD=2(55^{\circ})[/tex]

[tex]{\angle}PCD=110^{\circ}[/tex]

Thus, the measure of arc PD is [tex]110^{\circ}[/tex].

Hence, option (C) is correct.

The measure of arc PD is 110. So, The correct option is option C.

Angles formed by drawing lines from the ends of the diameter of a circle to its circumference form a right angle, therefore

90° = 135° + ∠DEP

∠DEP = 50°

Now, here is given,

∠FEP = 35°

∠FED = ∠FEP + ∠DEP....(1)

Plug the value of ∠FEP = 35° in equation (1),

∠FED = 90

90 = 35 + ∠DEP

∠DEP = 55

∠PCD = 2∠PED

∠PCD = 2 (55)

∠PCD = 110

Therefore, the measure of arc angle PCD is 110.
