Answer:

n = 3

Step-by-step explanation:

9{n+2(n-2)} = 45

Start with the numbers on the inner most pair of parentheses

Multiply (n-2) by 2

9[n+2n-4] = 45

Add what is inside the parentheses

9[3n-4] = 45

Multiply

27n-36 = 45

Add 36 to both sides

27n = 81

Divide both sides by 27

n = 3

Hope this helps!

ANEK [815]

Answer:

65 yd

Step-by-step explanation:

The image of this walking path of Cristal is missing, so i have attached it.

From the image attached, we can see that the path "x" is the hypotenuse path a the triangle.

Thus, we can use pythagoras theorem to find the area. Thus;

x² = 16² + 63²

x = √(16² + 63²)

x = √4225

x = 65 yd
