Answer:
B
Step-by-step explanation:
Since you are given options, simply plug in numbers.
A won’t work because (-10+5) = -5 and 18 clearly is not divisible by 5.
B works:
(-7-2)(-7+5) = -9(-2) = 18
Answer:
x = -7
Step-by-step explanation:
(x-2)(x+5)=18
We can substitute the possible solutions in and see if they are true
x = -10
(-10-2)(-10+5)=18
-12 * -5 = 18
60 =18
False
x = -7
(-7-2)(-7+5)=18
-9 *-2 = 18
18 = 18 True
x = -4
(-4-2)(-4+5)=18
-6 *1 = 18
-6 = 18
False
x=-2
(-2-2)(-2+5)=18
-4 *3 =18
-12 = 18
False
