Distribute
a(b+c)=ab+ac so
-3(x-5)=-3x+15
-8(y+2)+-8y-16
-3(6-4b)=-18+12b
add them together
-3x+15-8y-16-18+12b
associative property
15-16-18-3x-8y+12b
add
-19-3x-8y+12b is the answer which is D

Expand the expressions:

-3x+15-8y-16-18+12b

Combine like terms:

-3x-8y+12b-19

Now, we have fully simplified this expression.  D is the correct answer.

(PLESE HELP) Factor the following expression. Simplify your answer.
mars1129 [50]

The factor of the expression 5p(p + 2)^{\frac{2}{3} }  + 4(p + 2)^{\frac{1}{3} } is(p + 2)^{\frac{2}{3} } (5p^{3}  + 10p^{2}  + 20p + 4)

To answer the question, we need to know what factorization is

<h3>What is factorization?</h3>

Factorization is the process of breaking down an expressing into a simpler form containing its factors.

Since

5p(p + 2)^{\frac{2}{3} }  + 4(p + 2)^{\frac{1}{3} }

Since (p + 2)^{\frac{1}{3} } is common, we factor it out. So, we have

(p + 2)^{\frac{2}{3} } (5p(p + 2)^{2}  + 4)

Expanding the bracket, we have

(p + 2)^{\frac{2}{3} } (5p(p^{2}  + 2p + 4) + 4) = (p + 2)^{\frac{2}{3} } (5p^{3}  + 10p^{2}  + 20p + 4)

So, the factor of the expression 5p(p + 2)^{\frac{2}{3} }  + 4(p + 2)^{\frac{1}{3} } is(p + 2)^{\frac{2}{3} } (5p^{3}  + 10p^{2}  + 20p + 4)

You plug in x for 3 so it would be 10(3) + 2, and 10 times 3 is 30 and 30 plus 2 is 32

Answer:

8cm

Step-by-step explanation:

Area of a triangle equals bh/2

If you plug in the data, you get

10=\frac{5}{2}*\frac{h}{2}

10=\frac{5h}{4}

40=5h

h=8
