Brooke paints the outsides of the square walls and triangular ceilings of her treehouse. What is the area?
Zielflug [23.3K]

Answer:

The answer is "216\ ft^2"

Step-by-step explanation:

Please find the graph file in the attachment.

The area of its tree house's outsides of the square walls and triangular ceilings is equivalent to four squares with four triangles,

\to A=4[(6)^2+\frac{1}{2} (6)(6)]\\\\

       =4[36+\frac{1}{2} (36)]\\\\=4[36+18]\\\\=4[ 54]\\\\=216\ ft^2

Which could be the first step in simplifying this expression? Check all that apply. (x^3x^-6)^2
allsm [11]
If the expression is what I understand it is, this is my answer. (x to the third times x to the negative sixth all squared)

First, i would simplify what is inside the parentheses. x^-6 is the equivalent to
1/x^6. Therefore, the expression inside the parentheses is a fraction: x^3/x^6.

When dividing numbers with exponents, just subtract the exponents. 
3-6= -3     so the simplification of the expression in the parentheses is 1/x^3.

To finish the problem, I would apply the square from outside the parentheses to the values inside them. In this way, the exponent would be multiplied by 2.

Our final answer is 1/x^6.
