Hey! Thanks for submitting your question to Brainly! 

You can use the formula, A = 2 \pi r h + 2 \pi r^{2}

Plug in 3 and 5

You get your answer, 150.8.

Solve (x - 5)2 = 3.O A. x = -51 1/3O B. x = 3 15O C. x = 5+:13O D. x = 8 and x = -2
Virty [35]

In order to solve the given expression follow these steps:

1. Take the square roots on both sides in order to get rid of the power on the left side:

√(x-5)² = ±√3

x - 5 = ±√3

2. add 5 on both sides:

x-5 + 5 = 5 ±√3

x = 5 ±√3

Then, the solution is x = 5 ±√3

Tony separates a number of paintbrushes, x, into 3 equally sized groups. He claims that this is the same as making a group 1/3 t
DochEvi [55]

Answer:

Size of each group = \frac{x}{3}

Step-by-step explanation:

Total number of paint brushes = x

Since each the three groups are equally sized, to get the number of paintbrushes in a group, we will have to divide the total number of paint brushes by 3

∴ We have, number of paint brushes in a group = \frac{Total number of paintbrushes}{3}\\

= \frac{x}{3}

this is also the same thing as saying \frac{1}{3}×\frac{x}{1}

This shows that the size of the new group is the same as \frac{1}{3} the size of the original group

Ron bought a piece of plastic that was 3 1/2 yd by 2 2/3 yd.
Paul [167]
Multiply base time height. Simply put B(H)=A

B=3 1/2
H=2 2/3

A=(3 1/2)(2 2/3)
A=28/3
A=9.3333

Hey can you please help me posted picture of question
Shalnov [3]
Answer:
x³ - 3x² - 18x

Explanation:
Before we begin, remember the following:
xᵃ * xᵇ = xᵃ⁺ᵇ

Now, for the given:
To solve thus question, we will simply multiply each term from the first bracket by each term from the second bracket and then combine like terms to get the final answer.

This can be done as follows:
(x + 3)(x² - 6x)
x(x²) + x(-6x) + 3(x²) + 3(-6x)
x³ - 6x² + 3x² - 18x
x³ - 3x² - 18x

Hope this helps :)
