a

step-by-step explanation:

8+10

step-by-step explanation:

you multiply 4 by 2 and 5 by 2

the answer is d

for problems like this theres an app, its photomath that explains the problem and gives the answer hope i

y∈r, 8> y≥0

hope i !

p.s the first bit only matters if you know what that means.

p.p.s brainliest would really
