1)Because if u add 8+4 which is 12 and u just leave the x with the 12 which is 12x which is ur answer.
2)if you multiply 4 and 2x or 4•2x which is 8x and you if u multiply 4 and 1 which is 4 and you are left with 8x+4 which is 12x.
Answer:
1001
Step-by-step explanation:
Square both sides to get the binomial out of the square root:
(√(2x + 8))² = (2)²
2x + 8 = 4
2x = 4 - 8
2x = - 4
Divide both sides by 2 to isolate the variable X:
x = - 4 / 2
x = - 2
Your answer is option C.
The slope
and a point
that the line goes through, give us a equation for the line:
