Question 10 • FL-1200700-Mathematics for College Algebra MIS

Two positive integers have a product of 176. One integer is 5 less than the other integer. Which equation can be used to find the value of x, the greater integer?

Answer
A
x2 + 5 = 176
B
x(x + 5) = 176
C
x(x – 5) = 176
D
x2 – 5 = 176

Explanation

Let x be the greater integer. Since the other integer is 5 less, it is x − 5. Their product is 176, so the equation is x(x − 5) = 176, which is choice C.
