A square has an area of 64 m². What is the length of each side?

anygoal [31]

Answer:

Step-by-step explanation:

The area of a square is length*width.

We can square root the area to get the length of each side. Since the shape is a <em>square</em>, the lengths are the same.

$\sqrt{64}$ =8

One side is <u>8m</u>.

Given the function ƒ(x) = 20x2 − 18x − 25, find ƒ(−1).

dlinn [17]

f(x) = 20x² - 18x - 25

f(-1) = 20(-1)² - 18(-1) - 25

= 20 + 18 - 25

= 13

Write the equation of a line that is perpendicular to y = -8 3 x + 4 and goes through the point (5, 2)

zhuklara [117]

Answer:

y = 3/8x + 1/8

Step-by-step explanation:

The slope of a perpendicular line is the opposite and reciprocal of the original slope.

-8/3 -> 3/8

Find the new y-intercept.

y = 3/8x + b

2 = 3/8(5) + b

2 = 1.875 + b

0.125 = b

y = 3/8x + 1/8

Best of Luck!
