The product of two consecutive integers is 90. Which equation can be used to find the two integers?

x^2 + x = 90

2x + 1 = 90

2x + x = 90

x^2 = 90

Verified Answer :

bcalle

two consecutive integers would be x and x+ 1
if you multiply them you have x(x + 1) = x^2 + x
if you want the product to equal 90 you get x^2 + x = 90
The first option is correct.

Answer:

The first option \(x^{2} +x=90\) is correct.

Step-by-step explanation:

Given:

The product of two consecutive integers is 90.

Let,

Two consecutive integers will be x and x+1

If you multiply them you have

             \(x(x+1)=x^{2} +x\)

if you want the product to equal 90 you get

            \(x^{2} +x=90\)

The first option is correct.
