Question

8(7n-2) -6(7n+1)

Explain please

Answer 1

8(7n - 2) - 6(7n + 1) = 14n - 22

Explanation:

8(7n - 2) - 6(7n + 1)

use the distributive property: a(b + c) = ab + ac

= 8 · 7n + 8 · (-2) + (-6) · 7n + (-6) · 1

= 56n - 16 - 42n - 6

combine like terms

= (56n - 42n) + (-16 - 6)

= 14n - 22

Answer 2

=> 14n - 22

Explanation:

8(7n-2) -6(7n+1)

=> 56n - 16 - 42n -6

=> 14n - 22
