this is the answer in the picture
What i can see the total amount is wrong
Answer:
0
Step-by-step explanation:
Multiplying the first equation by xy, we have ...
x^2 +y^2 = -xy
Factoring the expression of interest, we have ...
x^3 -y^3 = (x -y)(x^2 +xy +y^2)
Substituting for xy using the first expression we found, this is ...
x^3 -y^3 = (x -y)(x^2 -(x^2 +y^2) +y^2) = (x -y)(0) = 0
The value of x^3 -y^3 is 0.
A = 225 in^2
W = 13.75
15x16 = 240 in^2
240/13.75 = 17.45 in
the mirror would not fit in a space that is 15 by 16 inches since its approximately 13 by 17 inches
