2s -5488/s^2 = (2s*s^2)/s^2 -5488/s^2 = (2s^3-5488)/s^2
Since this thing is = 0,
0 multiply by its denominator is still 0
So 2s^3 - 5488 =0
s^3= 5488/2= 2744
s= cube root 2744

Multiply. (w-7) (w+4)
stira [4]

Use the FOIL (first, outside, inside, last) to expand the terms in the brackets.

(w - 7)(w + 4)

first: w × w = w²

outside: w × 4 = 4w

inside: -7 × w = -7w

last: -7 × 4 = -28

Now you add all the terms together to get:

w² + 4w - 7w - 28

This simplifies to give you:

w² - 3w - 28

Hope that helps! :)

Nina buys a small rug in the shape of a kite. The width of the rug is half its height. What are the width and area of the rug? (
Alenkinab [10]

Answer:

Width = 20\ in

Area = 400\ in^2

Step-by-step explanation:

Given

See attachment for kite dimension

Required

Determine the width and the area

From the attachment, the height of the kite is:

Height = 31\ in + 9\ in

Height = 40\ in

The width which is half the height is:

Width = \frac{1}{2} * Height

Width = \frac{1}{2} * 40\ in

Width = 20\ in

The area is:

Area = \frac{Height * Width}{2}

Area = \frac{40\ in * 20\ in}{2}

Area = 40\ in * 10\ in

Area = 400\ in^2
