Answer:
Step-by-step explanation:
im pretty sure its 124041/554
C and D
n = 5, n = -7/2
2n + 5 = l
n - 4 = w
A = l × w = 15
(2n + 5)(n-4) = 15
2n^2 - 8n + 5n - 20 = 15
2n^2 -3n - 35 = 0
(2n + 7)(n - 5) = 0
2n + 7 = 0 or n - 5 = 0
n = -7/2 or n = 5
all real numbers not equal to 0
all real numbers
-17x is the answer mark me brainliest
