Oop. Let's see about this one.

Answer:

side length = (x+11)

Step-by-step explanation:

area = x^2+22x+121

side length = sq rt (x^2+22x+121)

side length = (x+11)

Answer:

Step-by-step explanation:

basically, what they are asking you is to factor and then plug in the values (x=3; x=4) that they gave you.

first, you need to factor out the equation.

start with the original equation.

V=4x^3+10x^2+4x

factored form:

V= 2x(2x^2+5x+2)

next, you're going to want to plug in the values.

the answer asks for x=4, but you should do both.

v=2(3)(2(3)^2+5(3)+2)

do not forget to do the exponents before!

v=6(18+15+2)

v=6(35)

v=210 ft^2

that's the answer for if x was equal to 3.

V= 2x(2x^2+5x+2)

don't forget to write the original equation first.

V=2(4)(2(4)^2+5(4)+2)

V=8(36+20+2)

⬆is your answer! hope this helped!!

Answer:

last one because theres no slope just a y intercept

Answer:

$8,900

Step-by-step explanation:

You don't say anything about compounding. If this problem involves only simple interest, then the interest will be i = p*r*t and the account balance will be i + p.

Here i = $8,000*0.075*1.5 (representing 18 months)

         i + $900

At the end of 18 months there will be $8,000 + $900, or $8,900, in the account.

$8,900

Answer:

8v + 9v - v

Step-by-step explanation:

Solving all options...

8v + 6v + 3v

=> 17v

3(v + 2) + 11v

=> 3v + 6 + 11v

=> 6 + 14v

2(4v + 8v)

=> 8v + 16v

=> 24v

8v + 9v - v

=> 16v

The last option is the only one that equals 16v, therefore, it would be the right answer.

Step-by-step explanation:

question 1) equal angels

8+19)=(9x+9)

x=10°

8x+19=99°

question 2) equal angels

(3x-26)=2x

x=26°

3x-26= 52°

question 3) different angels

180-(x+10) = x+50

180-x-10=x+50

170-x=x+50

2x=120

x= 60°

x+10= 70°

x+50=120°

question 4) equal angels

3x-31=x+59

2x=90

x=45°

x+59=104°

question 5) equal angels

6x+3=7x-12

x=15°

6x+3=93°

The steps to simplify the expression is:

Step 1 :

x (x-7y) + 4y(x- 7y) + z (x- 4y)

Step 2:

x² - 7yx + 4yx - 28y² + zx - 4zy

Step 3:

x² -28y² - 3yx + zx - 4zy

A mathematical operation such as subtraction, addition, multiplication, or division is used to combine terms into an expression. In a mathematical expression, the following terms are used:

We have the Expression:

(x + 4y + z) (x - 7y).

Step 1 :

x (x-7y) + 4y(x- 7y) + z (x- 4y)

Step 2:

x² - 7yx + 4yx - 28y² + zx - 4zy

Step 3:

the second is a bit trickier,you need a ratio for finding how many would be in 224 groups.

100:224 = 61:x, or 61/100 = x/224

Cross multiply; 100x=13664

Answer: Mean Absolute Deviation Calculator

Instructions

This calculator computes the mean absolute deviation from a data set:

You do not need to specify whether the data is for an entire population or from a sample. Just type or paste all observed values in the box above. Values must be numeric and may be separated by commas, spaces or new-line. Press the "Submit Data" button to perform the computation. To clear the calculator, press "Reset".

What is the mean absolute deviation

The mean deviation is a measure of dispersion, A measure of by how much the values in the data set are likely to differ from their mean. The absolute value is used to avoid deviations with opposite signs cancelling each other out.

Mean absolute deviation formula

This calculator uses the following formula for calculating the mean absolute deviation:

$ MAD =\frac{1}{n} \sum_{i=1}^n |x_i-\bar{x}|$

where n is the number of observed values, x-bar is the mean of the observed values and xi are the individual values.

==============================================================

Explanation:

For now, let's ignore the 73 pounds.

The 13 ounces she gains is added onto the initial 3 ounces to get 3+13 = 16 ounces = 1 pound.

So we add this 1 pound onto the 73 pounds from earlier to get the answer to be 73+1 = 74 pounds

-----------------

We could write the steps out like this

(73 pounds, 3 ounces) + (13 ounces)

(73 pounds + 3 ounces) + (0 pounds + 13 ounces)

(73 pounds + 0 pounds) + (3 ounces + 13 ounces)

73 pounds + 16 ounces

73 pounds + 1 pound

74 pounds
