Answer 10

so it's based off combining like terms >.<
-8a^3b + 3a^2b^2 - 5
2 + 5a^2b^2
3a^3b + 7 - 9a^2b^2
3a^2b^2, -9a^2b^2 and 5a^2b^2 are like terms
so combine those and you get;
-a^2b^2
then combine -8a^3b and 3a^3b
so far
-a^2b^2 - 5a^3b
then there's 2 and 7 = 9
-a^2b^2 - 5a^3b + 9

Answer 11

so the answer is...???

Answer 12

these are the options.

-5a^3b - a^2b^2 + 2

-5a^3b + 8a^2b^2 + 4

-5a^3b - a^2b^2 + 4

Answer 13

lol there's no answer to the expression. The simplified version is what i put above, just rearrange the terms >.<

Answer 14

Oh there's a -5, so
-a^2b^2 - 5a^3b + 4

Answer 16

can you help me some more? life on the line right now

Answer 17

Yeah :)

Answer 18

Simplify:

a - {4b - [a - (5b - c) + 3c - (a - b - 9c)]}

Answer 19

a - (4b - a - 5b + c + 3c - a + b + 9c)
(PEMDAS)
combine like terms within the parentheses
4b - 5b + b = -3b
-a - a = -2a
c + 3c + 9c = 13c
a - (-3b - 2a + 13c)
a + 3b + 2a - 13c
3b + 3a - 13c

Answer 20

choices:



-a - 8b + 13c

a - 8b + 13c

a - 2b + 13c

-a - 2b + 13c

Answer 21

Let me look again..

Answer 22

a - 8b + 13c. This time i;m sure

Answer 23

thanks. I have a bunch of problems, and right now math is the biggest one. need some serious help right now.

Answer 25

Choose the product.

-6p^3(3p^2 + 5p - 1)



-18p^5 - 30p^4 + 6p^3

-18p^6 - 30p^3 - 6p

18p^3 + 6p^2 - 30p^4

-18p^6 - 24p^3

Answer 26

first one

Answer 27

Select the correct product.

(x^2 + 6x + 9)(3x - 1)



3x^3 + 17x^2 + 21x - 9

3x^3 - 17x^2 - 21x - 9

3x^3+ 19x^2 + 27x + 9

3x^3+ 19x^2 + 9x - 9

Answer 28

im just gonna say ultimate thank you's

Answer 29

3x^3 - x^2 + 18x^2 - 6x + 27x - 9
3x^3 + 17x^2 + 21x- 9

Answer 30

Perform the indicated operation.

(36m^2 - 60m + 25) ÷ (6m - 5) = _____



6m + 5

6m - 5 R. 50

6m + 15 R. 100

6m - 5

Answer 31

6m - 5 >.<

Answer 32

-x^2y^2 + x^4 + 4y^2 - 4x^2



(x - 2)(x - 2)(x + y)(x - y)

(x + 2)(x + 2)(x + y)(x - y)

(x + 2)(x - 2)(x + y)(x - y)

Answer 33
