Answer:
It's a.
Step-by-step explanation:
(a - 2b)^2 + 8ab
= a^2 - 4ab + 4b^2 + 8ab
= a^2 + 4ab + 4b^2.
((a + 2b)^2 = a^2 + 4ab + 4b^2.
P = printer cost
C = computer cost
P + C = 900
C = 3P
P + 3P = 900
4P = 900
P = $225
C = 3(225)
C = $675
Answer:
9x2 = 18
Step-by-step explanation:
Im not sure what you mean lol
10+3=13
