Square root of 81 = 9 because to find for the area of square you would have to multiple two equal length

Perimeter is the addition of all length of the square since square has four equal sides it makes it each 9cm there you multiply 9cm x 4 sides getting 36cm

What two consecutive integers have a sum of 75?

marshall27 [118]

Answer:

37 and 38.

Step-by-step explanation:

Let the smaller integer be x.

Thus, the larger integer is (x+1) since it is consecutive.

$x+(x+1)=75$

$2x+1=75$

Subtract both sides by 1:

$2x+1-1=75-1$

$2x=74$

Divide both sides by 2:

$\frac{2x}{2}=\frac{74}{2}$

$x=37$

To find the other number, simply add 1 to 37 to get 38.
