Question

What is the answer to 15-5x2+[4x(3+5)+8]

Answer 1

Answer: 45

Explanation:

I don't know if you mean the "x" as multiplication or as a variable, but I will assume it means multiplication.

First:

Calculate what is inside the brackets ( [ ] )

4x(3+5)+8

=4x8+8

=32+8

=40

Next:

15-5x2+40

=15-10+40

=5+40

=45
