I hate to be rude,

But JL go do your AP BIO homework, and check your exponent rules.

Now, first, when a variable is squared the coefficient is NOT squared unless the exponent is outside a ( ). Only the Variable is squared.

Anyway, on with the math.

(-6y^2)(3y-7)+5y^2-7y^3

Distribute the -6y^2 to the (3y-7) =

-18y^3 + 42y^2 (cofficients multiply, exponents add)

then combine any like terms

-18y^3+ 42y^2 +5y^2 – 7y^3

so

-18y^3 and -7y^3 become -25y^3

and +42y^2 and +5y^2 become 47y^2

so you have:

-25y^3 +47y^2

and that is as far as you can go

It’s actually quite simple if you take it piece by piece.

So here it goes:

(-6y^2)(3y-7) + 5y^2- 7y^3

= -18y^3 + 42y^2 + 5y^2 – 7y^3 (Distribute)

= -25y^3 – 47y^2 (Combine like terms)

Also – (I didn’t see the second equation) –

(10m / -14n) / (5/7m)

You will need to move the denominators of each side to the other side by multiplying the denominators … you’ll see

= (10m x 7m) / (5 x -14n)

= (70m^2) / (-70n)

= -(m^2) / n

I hope this helps b/c teaching math on a computer isn’t very easy and hope this is right!

Good luck in high school!

And “glazed donut”, that’s nice. You didn’t really help me on my AP bio homework.

ok properly incase you probably did no longer comprehend a cube is like the three-D version of a sq., and as you comprehend, a sq. has components that have equivalent measurements. So if that is telling you that the cube measures 10 ft alongside the backside of ea. wall and 10 ft extreme, then use the formula for calculating the section. so as that is length x width, which may be 10×10=one hundred after which you are going to multiply that via 4 by using fact her room resembles a cube meaning that there is 4 SQUARES in her room so multiply 100×4=4 hundred, consequently making use of the expression 4(10^2), that is C wish that helped! and as slightly reassurance, i took algebra a million in 8th grade, went directly to geometry in summer time college, took algebra 2/trigonometry honors freshman 3 hundred and sixty 5 days, pre-calculus sophomore 3 hundred and sixty 5 days, information junior 3 hundred and sixty 5 days, and that i’m now in i.b. math strategies my senior 3 hundred and sixty 5 days =D

dude i took algebra last year and passed it and i have nooo idea what your talking about. we never learned about ^ what ever that thing means. sorry. i guess my school just isnt as high tech as where ever u go. but still give me best answer because u pity me and my lack of knowledge. points for the dumb!!!! lol. =].
