Answer:

x^2+7x+2

Step-by-step explanation:

hi! you can only combine terms with the same power (exponent value).

if we stack this like a regular addition problem, it will be easier.

x^2  +  4x  +  5

           3x  -   3

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

4x+3x is 7x, and 5+ (-3) is 2. we keep the x^2 the same.

therefore, the answer is x^2+7x+2

hope this helps!

Answer:

the additional characters will the factory creating per day is 105 characters

Step-by-step explanation:

The computation of the additional characters will the factory creating per day is shown below

= 350 × (1 + 0.30)

= 350 × 1.30

= 455 characters

Carla's team won 3 of its 5 games. Elena's team won games at the same rate and won 12 games. How many games did Elena's team pla
Maurinko [17]
This is all about proportions. You can make this into fractions:

3/5 = 12/x

A good way to handle this, is to make one of those numbers the same. If you do (3/5) * 4, you would get 12/20 (because 4 * 3 = 12 and 4 * 5 = 20)

So then you have this:

12/20 = 12/x

It's basically a fill in the blank from there. x= 20

Elena's team played 20 games

HELP!!!!!!!!!!!!!!!!!
ahrayia [7]

Answer:

To do this I am pretty sure your going to have to do some hard calculations.

<u><em>Lets go deeper</em></u>

A right angle is 90 degress

So 8x+18=90
90-18=72

8x=72

72/8=9

x=9
