Question

Which of the following expressions is not equivalent to (-2)(8 +6+-3)?

Answer 1

Answer:

$b.)31\neq -22$

Step-by-step explanation:

Simplify each equation using PEMDAS:

Parentheses (x)

Exponents x²

Multiplication and Division, left to right × ÷

Addition and Subtraction, left to right - +

It is also important to follow PEMDAS when working within grouping symbols like parentheses.

Also, remember that two negatives make a positive, and when a negative and positive are multiplied, the result is always negative.

$(-2)(8+6+-3)\\\\-2*(8+6-3)\\\\-2*(14-3)\\\\-2*11\\\\-22$

Find which answer is not equal to -22.

a.) $(-2)(8+6)+(-2)(-3)\\\\-2*(8+6)-2*-3\\\\-2*14-2*-3\\\\-28-2*-3\\\\-28+6\\\\-22$

---------------------------------------------------

b.) $(-2)*(8+6)+(-3)\\\\-2*(8+6)-3\\\\-2*14-3\\\\-28-3\\\\-31$

---------------------------------------------------

c.) $(-2)(8)+(-2)(6)+(-2)(-3)\\\\-2*8-2*6-2*-3\\\\-16-2*6-2*-3\\\\-16-12-2*-3\\\\-16-12+6\\\\-28+6\\\\-22$

---------------------------------------------------

d.) $(-2)(8)+(-2)(6+-3)\\\\-2*8-2*(6-3)\\\\-2*8-2*3\\\\-16-2*3\\\\-16-6\\\\-22$

---------------------------------------------------

Option b is not equal to -22.
