Question

Which expression is equivalent to 2(−4.1s − 3.4)?

A -2.1s - 3.4
B -2.1s - 6.8
C -8.2s - 3.4
D -8.2s - 6.8

Answer 1

D because you multiply (2) into each value even if it has a variable

Answer 2

D

Explanation:

If you do (-4.1s - 3.4) first you get -7.5, and multiply that by 2 you get -15. The same answer is also for D, -15, because you use the sign (negative in this case) of the greater number.
