=23.55843798 ~you need this number left as it is for a more accurate answer.
Then you do
42^2-23.55...^2(which we know is 555)

In combining like terms, what do these equations equal?
tester [92]

Answer:

Look below. The answers are bolded!

Step-by-step explanation:

1.   <em>10x + 23</em>

5+6(2x+3)-2x

Distribute first!

5 + 12x + 18 -2x.

Now you can combine like terms.

23 + 10x



2.   <em>18x + 6</em>

3(4x+8) + 3(2x-6)

Distribute first!

12x + 24 + 6x - 18

Now you can combine like terms.

18x + 6



3. <em>-2x + 8</em>

(32-8x)

____ ___

     4

Divide 32 and -8x by 4.


32/4 = 8

-8x/4 = -2x


-2x + 8



4. <em>4x + 3</em>

24x+18

______

    6


Divide 24x and 18 by 6

24x/6 = 4x

18/6 = 3


4x + 3

Using the order of operations, what would be the first step:<br><br> 4−8÷1−3[3+(7−5)2]
jeka94

Answer:

(7-5)

Step-by-step explanation:

According to PEMDAS, parenthesis go first. But there are two sets of parenthesis so the one inside the other goes first.

Next would be [3+(2*2)]

Then, [3+4]

Then, -8/1

Then, -3(7)

So the question would be 4-8-21

Which gives you -25 as an answer.

I realize that you weren't asking for the whole thing but maybe there are follow up questions.

Sergio039 [100]

Answer:

3.56 cm

Step-by-step explanation:

<em>Cube</em> is a 3D closed structure in which each adjacent side is perpendicular to each other and every side is equal to each other.

Let the side of cube be a cm.

Please refer to attached image of cube for a clear look and feel of a cube with each side = a units.

Then, volume of cube is given by the formula:

V = a^3

Here, we are given that:

V = 45\ cm^3

\Rightarrow a^3 = 45\ cm^3\\\Rightarrow a =\sqrt[3] {45}\\\Rightarrow a ={45}^\frac{1}{3}\\\Rightarrow a = 3.56\ cm

So, the answer is, Side of each petit four is, a = 3.56\ cm.

3/4 x blank= 3/2
So then you can divide area by the given length
3/2 divided by 3/4= 2
And to check your answer you would put 2 in as your width
3/4 x 2= 6/4. And 6/4 reduces to 3/2
