Which One Doesn't Belong? Which expression does not belong with the others? Explain your reasoning.
1 answer:
The expression that does not belong to the other group of expression is (c) 7(-2)(-5)
<h3>What are expressions?</h3>Expressions are mathematical statements that are represented by numbers and/or variables
The expressions are given as:
- 5(−3)(−1)
- (−4)2(−6)(−2)
- 7(−2)(5)
- −20(−6)
Start by evaluating all 4 expressions
Notice that three of the expressions return a positive result, while one of them return a negative result
The negative expression is the odd one among the four expressions
Hence, the expression that does not belong is (c) 7(-2)(-5)

~~~~~~~~~~~~~~~~~~
A ( - 7 , - 9 )
B ( x , y )
M ( - 0.5 , - 3 )
= - 0.5 ⇒ <em>x = 6</em>
= - 3 ⇒ <em>y = 3</em>
<em>B ( 6 , 3 )</em>
8p-8=-9(2p+5)-9(6-3p)
p=91
