Question

Two positive integers are 3 units apart on a number line. Their product is 108.

Which equation can be used to solve for m, the greater integer?

a). m(m – 3) = 108  
b.) m(m + 3) = 108
c.) (m + 3)(m – 3) = 108
d.) (m – 12)(m – 9) = 108

Answer 1

Answer:

d)  the numbers are 9 and 12

Step-by-step explanation:

set each factor equal to 108:

m-12=108

m = 120

*************

m-9=108

m=117

*************

120 and 117 are 3 units apart

****************

9 x 12 = 108
