Question

6m+m-4(-2m+1-m) when m=-8

Answer 1

= 48+8−4((−2)(8)+1−8)
= 56−4((−2)(8)+1−8)
= 56−4(−16+1−8)
= 56−4(−15−8)
= 56−(4)(−23)
= 56−(−92)
= 148

The answer is 148! I hope this helps! :>

Answer 2

Equation: 6m+m-4(-2m+1-m) (remember: PEMDAS)
Plug in -8: 6(-8)+(-8)-4(-2(-8)+1-(-8))
Simplify: -48-8-4(16+9)
Solve inside the parenthesis: 16 + 9 =25
multiply 4 times 25: 4*25=100
simplify: -56-100
simplify: -156
you're answer is -156
