Find each difference and show work please !!

Answer:

X-19

Step-by-step explanation:

First you need to distribute the three into the numbers in the parenthesis,

(3 * x) + (3  * -5) - (2x + 4)

That then turns into,

3x - 15 - (2x + 4)

but we aren't done distributing yet, because the second set of parenthesis has a negative sign in front of it we also have to distribute that. (this is because the negative sign is really just -1)

3x - 15 + (-1 * 2x) + (-1 * 4)

that turns into,

3x - 15 - 2x -4

from here all we have to do is add like terms,

(3x - 2x) + (-15 + -4)

and that leaves us with: 1x -19 or x-19

Hope that helped :))

Lesson 16
Goshia [24]

Answer:

546 ft³

Step-by-step explanation:

In the figure attached, the top view of the pool is shown. It can be decomposed into a trapezoid which height is 12 ft and which bases are 9 ft and 11 ft; and a rectangle which height is 1.5 ft and and it base is 11 ft.

Area of the trapezoid: (9 + 11)/2 * 12 = 120 ft²

Area of the rectangle: 1.5*11 = 16.5 ft²

Total area: 120 + 16.5 = 136.5 ft²

Volume of the pool: Total area * deep = 136.5 * 4 = 546 ft³

The formula s= SA/6 squared gives the length of the side, s, of a cube with a surface area, SA. How much longer is the side of a
stiv31 [10]
The surface area (SA) of a cube can be written as:

SA = 6s²

From here we can write, the length of the side s as:

s= \sqrt{ \frac{SA}{6} }

For cube with surface area of 1200 square inches, the side length will be:

s= \sqrt{ \frac{1200}{6} }=10 \sqrt{2} inches

For cube with surface area 768 square inches, the side length will be:

s= \sqrt{ \frac{768}{6} }=8 \sqrt{2} inches

The difference in side lengths of two cubes will be:

10 \sqrt{2} -8 \sqrt{2}=2 \sqrt{2}

Rounding to nearest tenth of an integer, the difference between the side lengths of two cubes will be 2.8 inches.
