There is a square parking lot at the grocery store. The diagonal of the parking lot measures 8√2 ft. Find the perimeter of the parking lot.​

Step-by-step explanation:

The square forms two 45-45-90 triangles, where the diagonal of the square is the hypotenuse of both these triangles. In all 45-45-90 triangles, the sides are in the ratio , where is the hypotenuse of the triangle and represents each of the two other sides of the triangle (from the Pythagorean Theorem).

Thus, we know that represents the hypotenuse, which means that the side length must be feet. The perimeter is then

= 5

step-by-step explanation:

to find the 15th term substitute n = 15 into the nth term formula

= (- 3 × 15 ) + 50 = - 45 + 50 = 5
