8^-5 / 8^-3
= (1/8^5 ) / (1/8^3)
=1/8^2
answer is <span>A. one divided by the quantity eight squared</span>
(w-2)^2 = 63
FOIL left hand side:
(w-2)^2 = w^2 - 4w + 4
So,
w^2 - 4w + 4 = 63
w^2 - 4w - 59 = 0
Then use quadratic equation to get values of w = 2 + 3*root(7) and w = 2 - 3*root(7).

Step-by-step explanation:
Points to keep in mind when solving triangle problems.
An isosceles triangle has two equal sides and the angles opposite to those sides are also equal angles.
A triangle with all sides equal is called an equilateral triangle, which is also called equiangular triangle.
