Answer:
8a+96
Step-by-step explanation:
8(12+a)
= 96+8a
It is just the multiplication of vectors. We'll multiply corresponding pairs together. The general formula for the pairs of (
;
) and (
;
) is
*
+
*
= (-6)*(-3)+4*6=18+24=42
-5(2x+1)-2x-2=17
first, distribute
-10x-5-2x-2=17
combine like terms
-12x-7=17
get the x alone, eliminate the constant
-12x=24
divide out the -12 to get the x alone.
x=-2
