4 divided by 2 is equal to 2. A number that is 5 times that would be 10, which is 2x5.

Not sure if it's correct, but I hope it helps :)

Write an expression for the area of the shaded region in its simplest form. Show all of your steps.
patriot [66]
The area of the shaded region will be the area of the rectangle minus the area of the white square inside of it:

((x+10)(2x+5)) - ((x+1)(x+1))

First, FOIL both of the areas separately:

(2x^2 + 5x + 20x + 50) - (x^2 + x + x + 1)

Simplify within the parentheses by adding like terms:

(2x^2 + 25x + 50) - (x^2 + 2x + 1)

Now, subtract one equation from the other:

2x^2 + 25x + 50
-x^2  -    2x  -   1
= x^2 + 23x + 49

This will be the equation for the area.

Mike has a barrel in the barn to keep water for his cows. The barrel is 4.5 feet tall and has a diameter of 3 feet. Approximatel
sergiy2304 [10]

Answer:

Approximately 238\ gallons

Step-by-step explanation:

we know that

The volume of a cylinder (barrel) is equal to

V=\pi r^{2}h

in this problem we have

h=4.5\ ft

r=3/2=1.5\ ft -----> the radius is half the diameter

substitute

V=(3.14)(1.5^{2})(4.5)=31.7925\ ft^{3}

<u>Convert to gallons</u>

31.7925\ ft^{3}*7.5=238.44\ gallons

G(x) = x^2– 5x f(x) = 2x +1<br> Find (g - f)(x)
Brrunno [24]

Answer:

x^2 - 7x - 1

Step-by-step explanation:

g(x) = x^2– 5x

f(x) = 2x +1

(g - f)(x)

expand to get

gx - fx

Slot in the values

(x^2– 5x) - (2x +1)

expand

x^2 - 5x - 2x - 1

x^2 - 7x - 1
