Answer:

  • 20.6

Step-by-step explanation:

<u>Coordinates given:</u>

  • D(-3,2)
  • E(4,2)
  • F(4,-3)

<u>Plotted, these points give a right triangle with hypotenuse DF</u>

  • Distance DE = 4 - (-3) = 7
  • Distance EF = 2 - (-3) = 5
  • Distance DF = √(7²+5²) = √84 = 8.6

<u>Perimeter</u>

  • P = 7 + 5 + 8.6 = 20.6

Answer:

AP is 11.25 so the answer is F

Step-by-step explanation:

Since they are similar triangles (due to the ~ symbol)

You can write this:

AC/XZ = AP/XQ

since XZ=12

XQ=5

AC=27

you can write:

27/12=AP/5

then cross multiply:

27x5=135

135/12=11.25

AP is 11.25

You don't have to answer them all but help me out !!
Mandarinka [93]

Answer:

1. 10n

2. 3x^2z^2

3. 2(9n^3 - 3n^2 + 3n - 1)

4. (Put the same thing)

5. There are no common factors so it is completely factored out.

Step-by-step explanation:

For 1, you gotta find the gcf of the numbers and the variables. So, the common factor of 90, 70, 70, and -80 is 10. Nothing else greater than 10 divides these numbers. For the variables, only "n" is the GCF, as there is one "n" and all the other numbers have n^2 and etc.

For 2, same thing, you have to find the gcf for the numbers and the variables.

3. same thing ;-; (gcf is 2 btw, nothing divides the variables because 2 has no "n".

4. theres nothing that divides the numbers or the variables. So, the gcf is just 1.

Select the correct first step to solve the follow equation: −4(x−5)=−7x+10
Otrada [13]

Answer:

x = -10/3

Step-by-step explanation:

−4(x−5)=−7x+10

Use the distributive property to multiply −4 by x−5.

−4x+20=−7x+10

Add 7x to both sides.

−4x+20+7x=10

Combine −4x and 7x to get 3x.

3x+20=10

Subtract 20 from 10 to get −10.

3x=−10

Divide both sides by 3.

x = -10/3
