Answer:

Area= 530.66

Step-by-step explanation:

So first, you want to set up your equation...

3.14(13^2)

3.14(169)

A=530.66

Hope this helped!

answer

is 169then pie symbol ft^2 or you can write it as 530.66ft ^2

Step-by-step explanation:

you multiply 13 and 13 and that's 169 then you have to add pie on there which is 3.14 so you multiply that or just add the pie symbol and then you ft. squared

hope this helps

Answer:

cot= adjacent side/opposite side

Option B is correct.

Step-by-step explanation:

We need to identify trigonometric identity which is given by the formula adjacent side/opposite side

The trigonometric identity for tan is

tan=  opposite side/adjacent side

But We are given adjacent side/opposite side

Since cot is inverse of tan so, formula of cot is:

cot= adjacent side/opposite side

Option B is correct.

Step-by-step explanation:

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

x^3+3x^2-10x-24

Answer:

x^3+3x^2-10x-24

Step-by-step explanation:

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

multiply the first two together first

(x^2+2x-3x-6)(x+4) add like terms first

(x^2-x-6)(x+4)

then multiply

x^3+4x^2-x^2-4x-6x-24

add like terms

x^3+3x^2-10x-24

Answer:

By giving reasons to the statements

Answer:

Since it is not an equation you would combine like terms and the answer would be 3x + (-24)

Step-by-step explanation:

There is no answer technically, you're just simplifying

Answer:

Step-by-step explanation:

you can't solve you don't know what X is so x+ 2x + (-24) is the answer

Answer:

201° and 60°

Step-by-step explanation:

(2)

∠ FHG = [tex]\frac{1}{2}[/tex]( arc ES + arc FG ), that is

128° = [tex]\frac{1}{2}[/tex] ( 55 + FG ) ← multiply both sides by 2

256° = 55° + FG ( subtract 55° from both sides )

201° = major arc FG

(3)

The measure of the secant- tangent angle FTS is half the difference of the intercepted arcs, that is

∠ T = [tex]\frac{1}{2}[/tex] ( arc FS - arc US )

     = [tex]\frac{1}{2}[/tex] (170 - 50)°

     = [tex]\frac{1}{2}[/tex] × 120°

     = 60°

The simplification for the given expression is 16mn.

An algebraic expression can be obtained by doing mathematical operations on the variable and constant terms.

The variable part of an algebraic expression can never be added or subtracted from the constant part.

The given expression is as below,

2 x m x n x 8​

Since multiplication of two algebraic terms can be done by first multiplying their coefficients and then the variables.

Apply the above mentioned rule to get,

2 x m x n x 8​

= 2 x 8 ​x m x n

= 16 x m x n

= 16mn

Hence, the given expression is simplified as 2 x m x n x 8​ = 16mn.

Answer:

see explanation

Step-by-step explanation:

The opposite angles of an inscribed quadrilateral are supplementary, thus

5x + 20 + 7x - 8 = 180

12x + 12 = 180 ( subtract 12 from both sides )

12x = 168 ( divide both sides by 12 )

x = 14

Thus

∠ RQP = 10x = 10(14) = 140°

∠PSR = 180° - 140° = 40° ( opposite angles are supplementary )

∠ SRQ = 7X - 8 = 7(14) - 8 = 98 - 8 = 90°

∠ QPS = 5x + 20 = 5(14) + 20 = 70 + 20 = 90°

Answer:

x = 11

General Formulas and Concepts:

Pre-Algebra

Step-by-step explanation:

Step 1: Define equation

5x + 9 - 3(x - 1) = (3x - 13) + (4x - 30)

Step 2: Solve for x

Step 3: Check

Plug in x into the original equation to verify it's a solution.

Here we see that 34 does indeed equal 34.

∴ x = 11 is a solution of the equation.

Answer:

x=11

Step-by-step explanation:

[remember: (-)(-) is (+) , (-)(+) is (-) , (+)(+) is (+)]

5x + 9 – 3(x-1) = (3x –13) + (4x -30)

5x + 9 -3x + 3 = 3x -13 + 4x -30

5x -3x + 9 + 3 = 3x + 4x -13 -30

2x + 12 = 7x - 43

2x - 7x = -43 - 12

-5x = -55

x = -55/-5

x = 11

Answer:

75

Step-by-step explanation:

86+79+68+83=316

391-316=75

Answer:

75 newspapers

Step-by-step explanation:

391 is equal to the combination of all the newspapers Nicholas sold over those 5 days. This can be written as an equation:

391 = 86 + 79 + 68 + 83 + x

x represents the number of newspapers Nicholas sold on Thursday.

Now let's solve for x:

First, combine like terms:

391 = 316 + x

now subtract 316 from both sides to isolate x:

391 - 316 = 316 - 316 + x

75 = x

Nicholas sold 75 newspapers on Thursday.

Answer:

area = w² + 8w

Step-by-step explanation:

the equation for calculating the area of something is:

area = length x width

length = 8 + width

area = (8 + width) x width

I will use w instead of width

area = w² + 8w

we can solve for w:

240 = w² + 8w

w² + 8w - 240 = 0

(w - 20) x (w + 12) = 0

so we know that the length of the pool is 20 feet and the width is 12 feet
