The product of two consecutive integers is 72. the equation x(x + 1) = 72 represents the situation, where x represents the smaller integer. which equation can be factored and solved for the smaller integer?
x2 + x – 72 = 0
x2 + x + 72 = 0
x2 + 2x – 72 = 0
x2 + 2x + 72 = 0

X(x + 1) = 72
Expanding the brackets, we get:

Subtracting 72 from both sides, gives:

This is the required equation to be factored and solved .

X(x + 1) = 72

x² + x = 72

x² + x - 72 = 0

The first option from the top.

1. isolate the variable, in this case, d. subtract 35.5 on both sides of the equation.2. 52 subtracted by 35.5 is 16.53. therefore your answer would be d= 16.5this is the basics of pre algebra, isolating variable through adding, subtracting, multiplying, and dividing, if you have any other questions to ask just comment!
