Question

a(b + c),if a = 3, b = -2, and c = 5

Answer 1

substitute the values
3(-2+5)=9

Answer 2

Substitute
You have 3(-2 + 5)

Step 1 : 3 + -2 = 1
Step 2 : 3 + 5 = 8
Step 3 : 1 + 8 = 9

Your answer = 9

Answer 3

you can do this 2 ways. the first way is
pedmas. Do the parens first:
(-2+5) which is the same as 5-2, simplifies to 3
you now have
3*3
which is 9

the other way is to "distribute" the 3 in 3(-2+5)
that means multiply 3 times each number inside the parens
3*-2 + 3*5
simplify to get
-6 + 15
and 15-6 = 9
just like before.
