Question

Simplify by combining like terms.6x + 2xy + 5x2 - 3x + 9xy

Simplify using the distributive property.

4(x2 + y) + 2(5x2 + y)

Simplify.

(4a + 3b) - (5a - 8b)

Simplify:

49x3y4

______

7xy

Simplify:

6m3n4 + 8m2n

___________

2m2n

Simplify the following. Explain each step in complete sentences.

5x2(7x + 2x4)

Thank you for ever who do this. I just HAT MATh! LOL

Answer 1

I know it is late

1.

at the x terms together and the xy terms together

3x+11xy+5x^2

2.

4x^2+4y+10x^2+2y

add like terms

14x^2+^y

3. distribute the negative sign into the term

4a+3b+5a+8b

now add like terms

9a+11b

4. first Davide 49 by 7 and you get 7

now add x^-1 y^-1 to the top and bottom and you get x^2 y^3

so the answer is 7x^2 y^3

5. first you get separate the top two terms into two different terms by putting the denominator under both of them so it looks like this

6m^3 n^4       8m^2

-------------    + -------

2m^2 n           2m^2n

now work it out with the steps shown above

3mn^4  + 4n

6.ok im not going to explain it (it is done in above problems just rearange the sentances to fit this problem)

distribute the 5x^2

35x^2+10x^4
