The answer is incorrect.

The square of binomials is:
(a + b)² = a² + 2ab + b

In (5x³ + 3)², a = 5x³ and b = 3

Substitute it in the formula for the square of binomials:
 (5x³ + 3)² = (5x³)² + 2 * 5x³ * 3 + 3² = 
                 = 25x⁶ + 10x³ + 9

Louise’s answer is 25x⁶ + 9, which is incorrect.

Answer:

I would say not here D.

Step-by-step explanation:

Because I found the area of the base first *the square* which is 4 x 11 = 44 and the rectangles are  4 x 14= 56 x 2 since there are 2 rectangles is 112. Then the triangles are 11x14=154/2=77 x 2 since there are 2 triangles is 154. Then we add up all those numbers 44+112+154= 310 not 308 *C*.

Hope I was able to help!
