Answer:
D) 2x²+4x-30
Step-by-step explanation:
You would multiply x and 2x; x and -6; 5 and 2x; 5 and -6
(x)(2x) = 2x²
(x)(-6) = -6x
(5)(2x) = 10x
(5)(-6) = -30
Now just put it back in the order that it was listed in the equation starting with (x)(2x)
This would give you 2x²-6x+10x-30
Simplify even further to get 2x²+4x-30
Answer: 4
Step-by-step explanation:
We can plug in the x and y values into the expression.
Then, we get 2*(-4) + 12.
Because of the order of operations, we calculate 2* -4 first to get -8 +12.
Lastly, we add -8 and 12 to get 4.
