<span>In the question "Which equation results from taking the square root of both sides of (x – 9)2 = 81?" The correct answer is x - 9 = +/- 9.
Taking the square root of both sides of the equation (x - 9)^2 = 81 will give:
sqrt(x - 9)^2 = sqrt(81)
x - 9 = +/- 9
Solving the equation results in two equation:
x - 9 = 9 and x - 9 = -9
x = 9 + 9 and x = -9 + 9
x = 18 and x = 0</span>
Let y = x^2 - 1
x^2 = y + 1
x = sqrt(y + 1)
so f^-1(x) = sqrt (x + 1) (answer)
Answer:
64
Step-by-step explanation:
Youd do 8x8 because the base of the triangles are 8 and a square has equal sides all around
One inch is a whole number so the decimal equivalent for it would just be 1.0 inches. If you have to convert it into cm it would be 2.54cm. But Could you elaborate if something is missing
