The height of the higher board above the water surface is 12 feet.

The distance from the high dive to the bottom of the deep end is 24 feet.

<h3>What does division mean?</h3>

Division is the process of dividing a number into equal parts using another number. The sign used to denote division is ÷.

<h3>What is the height of the higher board above the water surface?</h3>

In order to determine the height of the higher board, divide the height of the lower board by 25%.

Height of the higher board = 3 feet / 25%

3 / 0.25 = 12 feet

<h3>what is the distance from the high dive to the bottom of the deep end?</h3>

12 feet + 12 feet = 24  feet

X^4-64=0<br>The examples we did in class had solutions like "x=+-2" and "x=+-i(square root)3.​
hammer [34]

Answer:

Step-by-step explanation:

This isn't the same thing although you will get some factors that have i in them

(x^4 - 64) factors using the difference of squares.

(x^2 - 8)(x^2 + 8) Both of these factor using the difference of squares.

(x^2 - 8): factors into (x + sqrt(8) )(x - sqrt(8) )

(x^2 - 8):  factors further (x + 2*sqrt2)(x - 2sqrt(2)

(x ^2 + 8) : (x + sqrt(8)i ) (x - sqrt(8)i )

(x^2 + 8) : (x + 2sqrt(2)i) (x - 2sqrt(2)i)

Final answer

(x + 2*sqrt2)(x - 2sqrt(2)(x + 2*sqrt2)(x - 2sqrt(2)

A) x + y = 17
B) x * y = -308

B) y = -308 / x Substituting this into A)
A) x -308 / x = 17
A) x^2 -308 = 17x
A) x^2 -17x -308 = 0
x = 28
y = -11
