Answer:

12x^4-15x^3+18x^2

Step-by-step explanation:

We are given the expression: -3x^2(5x-4x^2-6)

The first thing that can be done is to rearrange the numbers in the parenthesis so that it is in the descending exponents, so that our answer will match the options given..

When this is done, we get -3x^2(-4x^2+5x-6)

Now, we can distribute the -3x^2 to each of the terms in the parenthesis

-3x^2(-4x^2+5x-6)\\\\12x^4-15x^3+18x^2

Can anyone help me out in my homework. I would love to talk about these problems ​
katen-ka-za [31]

Step-by-step explanation:

(b) If F_G = m_1g, then

m_1g = G\dfrac{m_1m_2}{r^2}

Note that m_1 cancel out so we get

g = G\dfrac{m_2}{r^2}

Solving for m_2, we get

m_2 = \dfrac{gr^2}{G}

(c) I'm not sure what the problem is asking for but here goes. As r doubles, F_G becomes

F_G = G\dfrac{m_1m_2}{(2r)^2} = \dfrac{1}{4}\left(G\dfrac{m_1m_2}{r^2}\right)
