Simplify -3p3 5p (-2p2) (-4) - 12p 5 - (-8p3).

Well in order to simplify this you have to first do distributive property (this is when you multiply the outside number next to a parenthesis times the terms inside the parenthesis) when you do this you will get -3p3+5p+(4p2)-12p+40p3 see how there is still 1 parenthesis well lets do that one to finish with the distributive property -3p3+20p3-12p+40p3.... now you have to add common like terms the only common like terms are -3p3, 20p3 and 40p3 so lets add or subtract those up to get 57p7, since -12p doesn't have any we leave it as it is... SO your last answer should be 57p3-12p

Hope this helps

Simplify into one fraction -2/x+3 - 4/x-5

sergiy2304 [10]

Multiply and divide by the product of the denominators.
$\dfrac{-2}{x+3}+\dfrac{-4}{x-5}=\dfrac{-2(x-5)-4(x+3)}{(x+3)(x-5)}\\\\=\dfrac{-6x-2}{x^{2}-2x-15}$

A box contains 20 equal-sized balls, numbered 1 to 20. Two balls are drawn at random simultaneously. What is the probability tha

jolli1 [7]

Answer:

P = 0,7947 or 79,47%

Step-by-step explanation:

We have 20 balls, the total possible outcomes drawn two balls simultaneously is:

C = m! /n! *( m - n )!

C = 20!/2! *( 20 - 2)!

C= 20*19*18!/ 2* 18!

C = 20*19/2

C = 190

Now the number of successful outcomes x ( those where balls differ by more than 2 is)

x = total numbers of outcomes - 20 ( outcomes differing in 1 ) - 19 (outcomes differing in 2 )

x = 190 - 39

x = 151

Then the probability of drawing tw balls with numbers differing n mr than two is

P = successful outcomes / total outcomes

P = 151/190

P = 0,7947 or 79,47%

50. Error Analysis for each of the past four years, Paulo has grown 2 in. every year, He is now 16 years old and is 5 ft 10 in.

mojhsa [17]

Answer:

I'd say that it's a good start, but he is assuming that his rate of growth will remain the same.

Since there are relatively few people 6'10" tall, it's likely that his extrapolation is too high.

Maybe if he could study the growth rates and heights at various ages of people who did achieve 6'10" height, he would have a sounder basis for his theory.
