Answer:  Like terms are combined together in algebraic expression so that the result of the expression can be calculated with ease. For example, 7xy + 6y + 6xy is an algebraic equation who's like terms are 7xy and 6xy. Therefore, this expression can be simplified by combining like terms as 7xy + 6xy + 6y = 13xy + y.

Step-by-step explanation:

Answer:

If in a equation there are numbers that have the same letters you can just add them or subtract them depending on the signs.

Step-by-step explanation:

For example this equation:

2x + 7b - 7x + 9b + 1a - 22a

So you just put them in different categories(Remember to bring them with the sign that's in front of each number) after that you just add or subtract them

category x(only numbers that have x's go here):     +2x-7x  = -5x

category b (only numbers that have b's go here):    +7b+9b = +16b

category a (only numbers that have a go here):       +1s-22b = -21a

now just put them in the same equation:

-5x+16-21a

and done!^^

Hope this example helped~

Answer:

[tex]2\sqrt{13}[/tex]

Step-by-step explanation:

Square root of 52

_________________

When finding square root, we always have to find one number that multiplies by itself twice to get the number in the square root.

No number does this for 52, so we have to use the GCF prime, which is :

[tex]\sqrt{2^2} \sqrt{13}[/tex]

Apply the radical rule for [tex]\sqrt{2^2}[/tex] :

[tex]\sqrt{2^2} =2[/tex]

Therefore :

[tex]2\sqrt{13}[/tex]

=-8y^9*-27x^6y^3z^6

=216x^6y^12z^6

Answer: I think the greatest common factor is 4x^2

Step-by-step explanation:

Find the numerical common factors. Which are 8, -12, and 20. Find the variable common factors for x^4, x^3, and x^2. Multiply them together. Then break down the factors on both sides and pick the biggest one. Finally multiply them together. (I’m sorry, I’m very bad at explaining things.)

Given: [tex]sinθ%20%3D%20%5Cfrac%7B15%7D%7B17%7D[/tex] = [tex]\frac{15}{17}[/tex]

Awnser: tan theta 15/8.

Step-by-step explanation:

AC = 17

AB = 15

BC = ?

By Pythagoras theorem:

AC² = AB² + BC²

17² = 15² + BC²

289 = 225 + BC²

BC² = 289 – 225

BC² = 64

BC = √64

BC = 8

The value of tanθ = 15/8

Answer:

C.

Step-by-step explanation:

To find which table is correct, you first have to plot the graph. First, pick some easy points on the X axis to graph. Some of these points could be -4, 0 and 4. Now you need to fill in the equation.

Y = -1/2*-4 - 2  = 0

Y = -1/2*0 - 2   = -2

Y = -1/2*4 - 2   = -4

Now you can plot the points and draw your line. Once you have done this, you check each table and see if all the points match up. Doing so would give you answer C.

Also the graph from the equation can be seen below

Answer:

Step-by-step explanation:

Answer:

Step-by-step explanation:

To get the new price of the car multiply the original price by the percent increase in decimal form  +1. 11% in decimal form is 0.11 = 11/100. Add one to this and you get 1.11 = 1 + 0.11. So now multiply $49,800 * 1.11 = $55,278. If the problem had said they decreased the price by 11% you would use 1 - 0.11 = 0.89 because 89% is 11% less than 100%.

hope that helps my man

14 is the answerr

Answer:

14

Step-by-step explanation:

because u bring the 8x to 10x which would be 2x. and the u bring the 19 to nine, and it would be 28. u take away the 2 and bring it to the 28, and divide it by 2. u would get 14
