The sum of three consecutive even integers is 72. let x represent the first integer, x + 2 represent the second integer, and x + 4 represent the third integer. which equation can be used to find the first integer? 3x + 6 = 72 3x = 2x + 6 2x + 64 = 72 3x + 72 = 2x + 6

3x + 6 = 72

Step-by-step explanation: Three consecutive even integers can be represented as followed.

X → first integer

X + 2 → second integer

X + 4 → third integer

Since the sum of our three consecutive integer is 72, we can set up an equation to represent this.

X + X + 2 + X + 4 = 72

Now, we can simplify on the left.

3x + 6 = 72

Therefore, 3x + 6 = 72 would be the equation.

step-by-step explanation:

use pothagarean therom

a^2+b^2=c^2 so first ac

acm is a right triangle because c= 90°

and am (the hypotenuse or c) =16+9 =25

but there is not enough info we need another angle or side length
