Answer:

(x-4)^2 -9

x^2+8x+7

x(x+8)+7

Step-by-step explanation:

(x+7) (x+1)

distributive property

x^2+ x+7x+7

combine like terms

x^2 +8x+ 7

Then solve each expression to find the one equivalent to x^2 + 8x+ 7

x=-7 and x+-1

Ella and Jake love to skateboard. They created a frame for the ramp and then covered it with wood.
Orlov [11]

Answer:

Step-by-step explanation:

  • Two triangular ends
  • Area of one = 1/2 b * h
  • b =1.2
  • h =0.9
  • Area = 1/2 * 1.2 * 0.9 =   0.54 sq meters
  • Area of 2  = 2 * 0.54                                      1.08

Area bottom

  • L = 3.5 m
  • w = 1.2
  • Area = L * W
  • Area = 3.5 * 1.2
  • Area =                                                              4.2

Area Back

  • L = 3.5
  • W = 0.9
  • Area = 3.5 * 0.9
  • Area =                                                                     3.15

Area Slanted piece

  • L = 3.5
  • w = 1.5
  • Area = L * W
  • Area = 3.5 * 1.5 =                          <u>                         5.25</u>

Total  = 5.25 + 3.15 + 4.2 + 1.08 =                               13.68
