Factor 36m^3-6m^2p^2-6mp+p^3

LenaWriter [7]

$36=6\cdot 6\\m^3=m^2\cdot m\\p^3=p^2\cdot p\\\\36m^3-6m^2p^2-6m\cdot pp+p^3=6m^2\cdot6m-6m^2\cdot p^2-6mp+p^2\cdot p\\\\=6m^2(6m-p^2)-p(6m-p^2)=\huge\boxed{(6m-p^2)(6m^2-p)}$

In an apartment complex with 28 units, 19 of the renters keep a pet. What percentage does not keep a pet?

Aleks04 [339]

If 19 out of 28 renters keep a pet, there are $28-19 = 9$ renters who don't keep a pet.

Whenever you have a subset of some set, and you want to know which percentage of the set the subset represents, you simply have to compute

$\dfrac{\text{number of elements in the subset}}{\text{number of elements in the set}}\times 100$

So, in your case, you're wondering what percentage of 28 does 9 represent. So, the formula becomes

$\dfrac{9}{28}\times 100 = 0.32\overline{142857}\times 100 = 32.\overline{142857} \approx 32.14\%$

State what additional information is required in order to know that the triangles are congruent by SAS

zalisa [80]

<h3>You are correct. The answer is the second choice.</h3>

BC = JC by the single tickmarks shown

CD = CD because of the reflexive property

The angles between these two pairs of sides, that you've marked in the second answer choice, are needed to use SAS (side angle side).

See the diagram below. In the diagram, angle BCD (green) is between segments BC and CD. Also, angle JCD (blue) is between JC and CD.
