BRAINLIESSTTTT ASAP !!!!!!!!!!

Part A: The area of a square is (9x^2 + 24x + 16) square units. Determine the length of each side of the square by factoring the area expression completely. Show your work. (5 points)

Part B: The area of a rectangle is (16x^2 − 25y^2) square units. Determine the dimensions of the rectangle by factoring the area expression completely. Show your work. (5 points)

Respuesta :

9x^2 + 24 x + 16 = 0 

(3x +4) (3x + 4) =  0

x=-4/3

are you sure part A doesn't have a negative somewhere? 

9x^2+12x+12x+16 this works just double checking

b)

16x^2 - 25y^2 =  0


(4x-5y)(4x+5y)= 0 


hope this helps
