Question

Find the value of each expression when a=-2 b=-3 and c=5

5a-4b+6c

Answer 1

Substitute the values in.

5(-2) - 4(-3) + 6(5). 

5 × -2 = -10.
4 × -3 = -12
6 × 5 = 30.

The expression is therefore -10 - -12 + 30, or -10 + 12 + 30.

Answer 2

I think it's 32 lol bc 5(-2) is -10, -4(-3) is 12, and 6(5) I'd 30. -10+12 is 2, then 2+30 is 32.
