What substitution should be used to rewrite 16(x + 1)2 - 22(x + 1) - 3 = 0 as a quadratic equation?

see explanation

Step-by-step explanation:

Given

16(x + 1)² - 22(x + 1) - 3 = 0

Using the substitution u = x + 1, then

16u² - 22u - 3 = 0 ← quadratic equation in standard form

d is the correct answer

step-by-step explanation:

x= 8 because 3x = 3 * 8, and 3*8 = 24

so a parallelogram is just like a square base times height. multiply 40 and 39 to get 1560 inches.

a triangle is base times height divided by two. so multiply 7.9 and 5 and then divide it by 2 to get 19.75inches.

the kite can be split into two separate triangles and added together to get the total area. 30 x 4 /2 which equals 60. make sure to double it for the two triangles making 120.
