A rectangle has an area of 40 square units. The width of the rectangle is (n+3) and the height is n. What are the possible dimensions? Use factoring. A. (x+2)(x-20)
B. (x-8)(x-5)
C. (x+8)(x-5)
D. (x-2)(x+20)

x = -4

step-by-step explanation:

- 20 - 4(x + 3) = 4x

=> -20 - 4x - 12 = 4x

=> - 32 -4x = 4x

=> -32 = 4x + 4x

=> - 32 = 8x

=> -32/8 = x

=> -4 = x

the functions have the same rate of change i think. i narrowed it down to this answer and "the rate of change of tour 1 is greater" but i got it wrong using that answer so im assuming its the answer above. (this is a question i also answered from the iready site if anyone needs a reference)
