Question

Please help ASAP!!! Thanks! :)
(−3)(a+x), if a=8, x=−10

Answer 1

-3(8-10) subtracting is the same as adding the opposite

-3(-2) multi. Negative times a negative becomes a positive

6

Answer 2

Answer:

Step-by-step explanation:

First we should solve the problems inside the bracket (a+x). Since a=8 and x=-10, (a+x) = (8+(-10)). (8+(-10))= (8-10). Then it is only a matter of subtraction and multiplication. (8-10)=(-2). Now we have clear numbers instead of variables, so (-3)(-2)=+6 (since two brackets with no sign in between will multiply the contents inside each other together.). I hope this was helpful!

TL;DR: (-3)(a+x)=(-3)(8+(-10))=(-3)(8-10)=(-3)(-2)=+6.
