Question

((-7) + 7) / (-9(2)) x (8-(-3)(2))

a) -2
b) 2
c) 4
d) -4

Answer 1

The calculation of the student's question results in 0, which is not an option presented. This suggests a possible error in the problem, as solving the given expression step by step does not yield any of the options a) -2 b) 2 c) 4 d) -4.

Step-by-step explanation:

The student's question involves simplifying a mathematical expression using the order of operations and substitution. The solution, however, appears to be related to solving quadratic equations, which is not directly applicable to the original expression given by the student. Nevertheless, let's proceed to solve the student's expression step by step:

( (-7) + 7 ) / ( -9 * (2) ) * ( 8 - ( -3 ) * (2) )

First simplify the parentheses:

• (0) / ( -18) * (8 + 6)

Then multiply and divide as follows:

1. 0 / -18 = 0
2. 0 * 14 = 0

This gives us a direct answer of 0, which is not given in the options a) -2 b) 2 c) 4 d) -4. This indicates there might have been a misunderstanding or a typo in the problem as presented.
