which one do you think isn't equivalent to 2x+6?
OpenStudy (parissfrance09):
I dont know :(
OpenStudy (anonymous):
ok, lets look at the first choice
OpenStudy (anonymous):
what is x+x?
OpenStudy (parissfrance09):
ok

2x
OpenStudy (anonymous):
yep, and what is 2+2+2
OpenStudy (parissfrance09):
6x
OpenStudy (anonymous):
huh? there is no x value
OpenStudy (anonymous):
2+2+2=6

so the first choice can be simplified to 2x+6
OpenStudy (parissfrance09):
thank you what about the rest and it says equivalent
OpenStudy (parissfrance09):
not equivalwn
OpenStudy (parissfrance09):
i have a lag sorry
OpenStudy (anonymous):
that's right, so we can rule out the first choice

let's simplify the second choice 2(x + 3)
OpenStudy (parissfrance09):
2x / 6
OpenStudy (anonymous):
nope. multiply 2 into (x+3)
OpenStudy (parissfrance09):
i did 2 goes it to x none cause they are different terms and 2 times 3 is 6
OpenStudy (anonymous):
2 times x is 2x

so it becomes 2x+6
OpenStudy (parissfrance09):
thats what i sai i said 2x/6
OpenStudy (anonymous):
2x+6 not 2x/6
OpenStudy (parissfrance09):
okay it looks like a divide sign
OpenStudy (anonymous):
ok, so we can rule out the second choice

lets look at the third choice
OpenStudy (anonymous):
does 2x + 22 equal 2x+6?
OpenStudy (parissfrance09):
no
OpenStudy (anonymous):
that means 2x + 22 is not equivalent to 2x+6
OpenStudy (parissfrance09):
thank you

That's the answer for question 1
OpenStudy (parissfrance09):
thats 2x + 2 to the power of 2
OpenStudy (parissfrance09):
npt 22
OpenStudy (anonymous):
The whole equation to the power of 2, or just the 2 to the power of 2
OpenStudy (parissfrance09):
just the 2

ok, so what's 2^2?
OpenStudy (parissfrance09):
the last one is 6 + 2x right?
OpenStudy (parissfrance09):
thats 2x + 6
OpenStudy (anonymous):
yep
OpenStudy (anonymous):
but what is 2^2?

OpenStudy (parissfrance09):
2x + 6
OpenStudy (parissfrance09):
thats a plus sign btw
OpenStudy (anonymous):
huh? no, i'm asking what is 2 to the power of 2 equal to
OpenStudy (parissfrance09):
6
OpenStudy (anonymous):
nope. It's the same as 2 times 2

OpenStudy (parissfrance09):
oh 4
OpenStudy (anonymous):
ya so what we have is 2x+4 for the third choice
OpenStudy (anonymous):
what can you do to 2x+4 to make it 2x+6?
OpenStudy (anonymous):
you add what to 2x+4 to make it 2x+6
OpenStudy (parissfrance09):
2

OpenStudy (anonymous):
that's right
OpenStudy (anonymous):
so for question 2 you can say that 2x+2^2 is the same as 2x+4. You add 2 to 2x+4 to get the desired 2x+6
OpenStudy (parissfrance09):
ok
OpenStudy (anonymous):
can you think of an equation for question 3?
OpenStudy (parissfrance09):
hold up

OpenStudy (parissfrance09):
no i mean 4x - 4^3
OpenStudy (parissfrance09):
or ^ 2
OpenStudy (anonymous):
nope. 4^2=16
OpenStudy (parissfrance09):
4x + 6^2
OpenStudy (anonymous):
There isn't a simple power that will give you 12

6^2 is the same as 6x6 which equals 36
OpenStudy (parissfrance09):
4x+6 +6
OpenStudy (anonymous):
That works
OpenStudy (parissfrance09):
okay
OpenStudy (anonymous):
4(x+3) is another

Then to solve 4x+6+6 just simplify it by adding the 2 six's
