Question

Somebody help me.. i need this done or im grounded.

Answer 1

Need what done? Best to start off presenting the actual problem with which you want help.

Answer 2

b. -6
c. 1/6
d. -1/6

2. Simplifly 3-2x/7 + 4x+5/7
a. 2x+8/14
b. 2x+8/7 <---
c. x+1/7
d. 2x+2/7

3. Simplify 6ab^6/4a^7b^10 * a^3b^4/2a^7b^6

4. Simplify 15x+3/27x-18 * 3x-2/5x+1
a. 7-2x/2x-18
b. 3
c. 7-2x/x-9
d. 5-15x/x+5 + 8x+8/x+5

Answer 3

7. 6a^8b^8/5a^6b^11 / 3a^4b^10/a^4b^4
a. 2a^2/5b^9
b. 2a^6b^4/5a^5b^7
c. 18a^6b^18/5a^5b^11
d. - 5/x-10

8. 11x/8-x
a. 3x/4-x + 10x/x-4
b. 7x/4-x
c. 7x/4-x
d. 13x/4-x

9. 4x-13/12x
a. 2x-1/6x +x+2/2x
b.4x+3/12x
c. 4x+3/6x
d. 3x+1/6x

10. Simplify using long division 11x/(x+8)(x-4)
a. 11/(x+8)(x-4)
b. 11x+16/(x+8)(x-4)
c. 11x+28/(x+8)(x-4)
d. 3/x+9 + 4/x-8

Answer 4

thats number 6

Answer 5

Thats alot

Answer 6

i know..

Answer 7

its a stupid assessment i gotta get done today.

Answer 8

Can you list what you think the answers are and we can validate? For 1, excluded values are those numbers that make the denominator zero, none of the options match in that one. It is "excluded" because division by zero is undefined.

Answer 9

Is the problem for 1) maybe \(\cfrac{4}{6-x}\) or something like that?

Answer 10

no :/ it says 4x/6..

Answer 11

it should be 3/2 for number 1

Answer 12

those are the answers though. i looked at the problem but there wasnt anything different.

Answer 13

ok - number 1 doesn't look right
try 2
$$
\cfrac{3-2x}{7} +\cfrac{4x+5}{7}\\
=\cfrac{3-2x+4x+5}{7}\\
=\cfrac{8+2x}{7}
$$
So your answer for this one looks right.

Answer 14

okay thanks!

Answer 15

3)
Is the problem:
$$
\large{
\cfrac{6ab^6}{4a^7b^{10}} \times \cfrac{a^3b^4}{2a^7b^6}\\

}
$$
?

Answer 16

yes.

Answer 17

@ybarrap

Answer 18

Ok, if that is the problem for 3), simplifying results in
$$\large
\cfrac{3}{4a^{10}b^6}
$$
Again, this does not fit any of your options. Also, none of your options make sense, the 1st 2 involve the variables \(x\), which don't appear in the original problem and the last two aren't even simplified.
