vagabundo [1.1K]

Answer:-15 is correct

Step-by-step explanation:

(-6)-9 is the same as -6-9 since parenthesis aren’t really needed in thins case and if you use the order of operations you go left to right. So, -6-9=-15 because a negative- a negative= a negative.

Mrs drew wants to build a square sandbox with an area of 169 square feet. What is the total length of wood mrs. Drew needs to ma

Bezzdna [24]

Area of sandbox = 169 square feet

Area of square with side 'x' is given by the formula = $x^2$

We have to determine the total length of wood Drew needs to make the sides of the sandbox.

Total length of wood required would be equal to perimeter of sandbox.

Let 'a' be the side of the square sandbox.

So, Area of sandbox = 169

$a^2 = 169$

$a = \sqr{169}$

a = 13 feet

Total length of wood required to make sides of the sandbox = Perimeter of the square sandbox = $4 \times a$

= $4 \times 13$

= 52 feet.

Therefore, 52 feet of wood is required to make the sides of the square sandbox.
