Question

-8(2z - 70)
use z = 5 and c = 2

Answer 1

480

Explanation:

-8( 2(5) - 70)

-8 ( 10 - 70)

-80 + 560

480

Answer 2

480

Explanation:

So we have the expression:

`-8(2z-70)`

And we want to evaluate it for z=5 and c=2:

So:

`=-8(2(5)-70)`

Multiply within the parentheses:

`=-8(10-70)`

Subtract within the parentheses:

`=-8(-60)`

Multiply:

`=480`
