simplify
-6 x^{2} ÷ 12 - 2(-7)

a. -17
b. 35
c. -35
d. 11

Answer 1

11

Explanation:

Given:
`(-6^(2))/(12) -2(-7)`

Using PEDMAS rule to solve it.

Now, simplifying:

We first open parenthesis which is (-7) = -7

=
`(-6^2)/(12)-2* -7`

Now, we evaluate the exponent which is
`-6^2=-36`

Next, we divide -36 by 12 to get -3

=
`(-36)/(12)-2* -7 \\= -3 -2* -7`

Next, we multiply -2 and -7 to get 14

=
`-3 + 14`

Lastly, we add -3 and 14 to get 11

=
`11`

∴ Answer is 11
