Factor. Check by multiplying. x^2 - 3x

2 answers:

7 0

Both term has factor of x

So that would be x² - 3x = x·x - 3·x = x( x-3 )

You can check by distribute x back to x-3:

x( x-3 ) = x·x - 3·x = x² - 3x. So our answer is correct.

Final answer: x( x-3 )

Hope this helps.

When (81x^2/7) (2/9x^3/7) is simplified, it can be written in the form ax^b where a and b are real numbers. Find ab.

larisa86 [58]

Answer:

In improper form your solution will be $\frac{90}{7}$ . As a mixed fraction it will be $12\frac{6}{7}$ .

Step-by-step explanation:

The first thing we want to do here is to simplify this expression. After doing so, " a " and " b " should be multiplied to result in a possible improper fraction,

$\left(81x^{\frac{2}{7}}\right)\:\left(2/9x^{\frac{3}{7}}\right)\:$ - Apply exponential rule " $\:a^b\cdot \:a^c=a^{b+c}$ "

= $81\cdot \frac{2}{9}x^{\frac{2}{7}+\frac{3}{7}}$ - Combine fractions $\frac{2}{7}$ and $\frac{3}{7}$

= $81\cdot \frac{2}{9}x^{\frac{5}{7}}$ - Multiply the fractions, and simplify further

= $\frac{162x^{\frac{5}{7}}}{9}$ = $18x^{\frac{5}{7}}$ - This is out simplified expression

Now that we have this simplified expression, we can see that a = $18$ , and b = $\frac{5}{7}$ . Therefore, multiplying the two we should receive the improper fraction as follows,

$18 * \frac{5}{7}$ = $\frac{90}{7}$ - Note that this is in improper form. If you want your solution in a mixed fraction, it will be $12\frac{6}{7}$ .

How to get the answer to 3 1/2 ÷ 5 ( I need I step by step explanation :D )

Sati [7]

Answer: .28

Step-by-step explanation: First turn the mixed number into an improper fraction. so 3x2+1=7, 7 is the the top and the bottom stays the same (2) so it would now be 7/2 divided by 5 which would equal .28

PLS HELP WILL MARK BRAINLIST IF ANSWER IS CORRECT !! :) FILL IN THE BLANKS

andrew-mc [135]

Answer:

Part 1) The volume of the storage body is 576 cubic feet

Part 2) To find out how many boxes can she fit in the storage body, divide the volume of the storage body by the volume of each box

Part 3) Sheila can fit 64 boxes into the truck

Step-by-step explanation:

step 1

Find the volume of the storage body

we know that

The volume of the of the storage body is equal to the volume of two rectangular prism

The volume of a rectangular prism is equal to

$V=LWH$

First rectangular prism (top)

$V=(15)(6)(8-6)=180\ ft^3$

Second rectangular prism (bottom)

$V=(15-4)(6)(6)=396\ ft^3$

The volume of the storage body is

$V=180+396=576\ ft^3$

step 2

we know that

To find out how many boxes can she fit in the storage body, divide the volume of the storage body by the volume of each box

step 3

substitute the given values

$\frac{576}{9}= 64\ boxes$

therefore

Sheila can fit 64 boxes into the truck
