Answer:

x³ + 12x² + 35x

Step-by-step explanation:

"What is (x² + 5x) multiplied by (x + 7)?

First, we can convert this into an algebraic expression!

This can be written as:

(x² + 5x)(x + 7)

We can use the FOIL Method for multiplying binomials.

FOIL: First, Outer, Inner, Last

"A technique for distributing two binomials. The letters FOIL stand for First, Outer, Inner, Last. First means multiply the terms which occur first in each binomial. Then Outer means multiply the outermost terms in the product. Inner means multiply the innermost terms in the product, Last means multiply the terms which occur last in each binomial."

FOIL: First: x² × x

x² × x = x³

FOIL: Outer: x² × 7

x² × 7 = 7x²

FOIL: Inner: 5x × x

5x × x = 5x²

FOIL: Last: 5x × 7

5x × 7 = 35x

Add Everything Together!

x³ + 7x² + 5x² + 35x

Simplify:

x³ + 12x² + 35x

What is the mean absolute deviation of 275, 252, 248, 240, 240, 225, 215, 214, 189, 184

Sati [7]

Hi , if we want to find the M.A.D of the numbers shown , then we have to add them .
275+252+248+240+240+225+215+214+189+184=2,282
Then we have to divide the number by the total of numbers that we have.
2,282 ÷ 10 =228.2
Then we have to subtract 228.2 by each number that we have.
228.2-275=-46.8
228.2 - 252=-23.8
228.2 - 248=-19.8
228.2 - 240=-11.8
228.2-240=-11.8
228.2-225=3.2
228.2-215=13.2
228.2-214=14.2
228.2-189=39.2
228.2-184=44.2
Then we add those numbers , that gives us 0 , if you don't work with negatives numbers then your answer would be 228 , finally we divide that number by the total of numbers that we have , your answer is 22.8 , if you do work with negative numbers then your answer is 0.

Hi.

Step-by-step explanation:

Because this question is asking how much water the water tower can hold, it's asking for the volume of a cylindrical figure. Let's use this formula:

First, let's find our variables by plugging in our information.

Answer:

15x -45
3(5x -15)

Step-by-step explanation:

The expression can be fully factored as ...

3·5·(x-3)

Equivalent expressions can be formed by eliminating parentheses to give ...

15x -45

or by combining different pairs of factors:

3(5x -15)
5(3x -9)

Of course any of the terms can be broken apart and/or combined in different ways:

= 15(x -2) -15

= (7x -7) + 2(4x -19)
