Answer:
C. is correct
Step-by-step explanation:
Mono means one and 2nd degree is 2 as a exponent.
14 because a negative minus a negative is a positive; you add a line and change the sign
10+10=20 = length
20 + 18 = 38 width = 18 or 9 on each side
10 x 9 = 90
Answer 90
When you factor (x^2-4x-5), you get (x+1)(x-5).
10q-3r=14, 10q=3r-14 10q=3r/10+14/10
q=3/10r+7/5
