3-3x^2+6+3x+1+4x+2x
combined like terms

Answers

Combining like terms must always be in descending order.

Start with the exponents.

As we see, there is no other exponents so we would leave it as such.

$-3x^2$

Progress on to the next greatest which are the variables.

Add all of the coefficients

$4x + 3x + 2x = 9x$

Lastly, move on to the single numbers.

Add them together as shown above, but this time there are no coefficients so it is just a matter of addition and subtraction

$3 + 6 + 1 = 10$

Therefore, the answer is:

$-3x^2 + 9x + 10$

Like terms are terms that are alike. 5x and 3x are like terms because they have a coefficient along with a variable. Like terms are terms that can be added together.

We are given:

$3-3x^2+6+3x+1+4x+2x$

Since the $x^2$ term can't be combined to anything, let's combine our x terms. Here is what we will combine:

$3x+4x+2x = 9x$

When combined, they equal 9x. So our expression is now:

$3-3x^2+6+1+9x$

Now, let's combine our regular numbers. We will be adding:

$3+6+1=10$

Now, our expression is even more simplified. We are left with:

$-3x^2+9x+10$

This is your final answer. Nothing can be combined further. Fun fact, this is in standard form and you will be using it in higher algebra.

A triangle has an area of 45 square units. Its height is 10 units.What is the length of its base?

Answers

Area = (1/2)*base*height

45 = (1/2)*base* 10

45 = base*5

45/5 = base

9 = base

base = 9

The length of the base is 9 units.

A circle is divided into nine equal parts.what is the angle measure of two of those parts

Answers

Solutions

A circle is divided into 9 equals parts. A circle is a round, therefore it has 360°. To solve the problem we have to use division.

360° ÷ 9 = 40

40° is the angle measure of two of those parts.

A whole circle is 360 degrees so 360 divided by 9 equals 40 so each part is 40 degrees so 40+40=80. Your answer is 80

6. Ivan saves 20% of his monthly paycheck for music equipment. He earned$335 last month.a. How much did he save for music equipment? Explain.b. If he uses $20.10 of what he earned to buy sheet music, what percent ofhis earnings is this amount? Explain.

Answers

20/100= .02.
.02 x $335.00 = $ 67.00
20.10/67.00 = .3 .3 x100 = 30%

This question is a bit hard too comprehend but I think we got it! ;D
If you know how too solve percentage word problems, you've got a great start! If you don't i'll still explain how! <3

Too solve percentages make it a decimal and multiply.
- This question : 355 x .20
* 71 $ of his paycheck goes into savings! :)

Now the rest is just plain ol' math :D

Subtract 20.10$ from 355$
- Then find the percentage! :)

Hope This Helped!! <3
