(2^3x^2 -  3) -  2  = 0 \\ \\  Factoring:  \ 8x^2-5 \\ \\   8x^2 - 5  = 0 \\ \\  Add \ 5  \ to \ both \ sides \ of \ the \ equation : \\ \\ 
                      8x^2 = 5 \\ \\ Divide \ both \ sides \ of \ the \ equation \ by \ 8: \\ \\ 
                     x^2 =  \frac{5}{8}  = 0.625 \\ \\ \boxed{ x  =\pm  \sqrt 5/8}

Write the standard equation of the circle with the given center that passes through the given point
Kitty [74]
Circle equation
(x - h)^2 + (y - k)^2 = r^2
Since radius isn't given use the center and point, with the distance formula, to find the radius.
D=sqrt((x2-x2)^2+)y2-y1)^2)
D=sqrt((1-0)^2+(2-6)^2
D=sqrt(1+16)
D=sqrt 17
radius = sqrt 17
(h, k) is the center and r is the radius
(x - 1)^2 + (y - 2)^2 = 17

Joe is 3 times as old as Pepe In how many years will Joe be only twice as old as Pepe ? How old are they now? How old will they
antoniya [11.8K]
Let x = Wally's age now

Then, 3x = Jose's age now

Wally's age 5 years from now = x+5

Jose's age 5 years from now = 3x+5

(x+5) + (3x+5) = 42

4x + 10 = 42

4x = 32 x = 8

Wally is 8 years old and Jose is 24.

(3³ x 5³)² - 2 

( 27 x 125)
² - 2 

125 x 27 = 3375

3375
² = 11,390,625

11,390,625 - 2 = 11,390,623
