X^2-64=0 solve for all real values of x

Hi there! Use the difference of two squares formula to solve the problem below:

From the equation, 64 comes from 8². Thus,

The question also asks you to solve for all real values. Thus,

Answer

circle area = pi * radius^2

if diameter = 10 then radius = 5

circle area = pi * 5^2

circle area = pi * 25

circle area = 78.5398163397 square units

step-by-step explanation:

the terms of a geometric sequence can be found by beginning with the first term and multiplying by the common ratio repeatedly. a recursive formula for a geometric sequence with common ratio r is given by an=ran−1 a n = r a n − 1 for n≥2 n ≥ 2 .
