Answer:
B.
Step-by-step explanation:
use distributive property
4*x + 4*3 = 4x+12
Answer: x = -3
Step-by-step explanation:
2y + x = -15
y = 2x
2y = 2(2x) = 4x
4x + x = -15
5x = -15
x = -3
Answer:
y=-4x-2
Step-by-step explanation:
y-y1=m(x-x1)
y-14=-4(x-(-4))
y-14=-4(x+4)
y=-4x-16+14
y=-4x-2
The simplest form for 3:12 is 4.
Answer:
8a^3.
Step-by-step explanation:
(a+b)^3=a^3+b^3+3a^2b+3ab^2
(a-b)^3=a^3-b^3-3a^2b+3ab^2
(a+b)^3+(a-b)^3=2a^3+6ab^2
According to the question
(a+b)^3+(a-b)^3+6a(a^2-b^2)
Put in the value
=2a^3+6ab^2 +6a^3–6ab^2
=8a^3
