28x^3-21x^2-12x^2-42x+9x+18=
28x^3-33x^2-33x+18
D is the correct answer
Answer:
12x^2-4x
Step-by-step explanation:
5x + 4x^2 - 9x + 8x^2
Combine like terms
4x^2+8x^2+5x-9x
12x^2-4x
Answer:1/5
Step-by-step explanation:
20/100=1/5
X + x + x + x + 2 + 2 = 24 Length: (x + 2) = 5 + 2 = 7 inches
4x + 4 = 24 Width: (x) = 5 inches
-4 -4
4x = 20
divide by 4 on both sides
x = 5
