Answer: 2p(-3p^2+4p-5)=-6p^3+8p^2-10p

Step-by-step explanation:

Given expression: 2p(-3p^2+4p-5)

We can use distributive property which says that:_

a(b+c)=ab+ac, where a ,b and c be any real numbers or variables.

Then,  2p(-3p^2+4p-5)=2p\cdot-3p^2+2p\cdot4p-2p\cdot5

=-6p^{1+2}+8p^{1+1}-10p

Now, we use product law of exponent which says that:-

a^m\times a^n=a^{m+n}

\Rightarrow\ -6p^{1+2}+8p^{1+1}-10p=-6p^3+8p^2-10p

Hence, 2p(-3p^2+4p-5)=-6p^3+8p^2-10p

If there is a really short way of doing this, I don't see it. The only way I know to do it is to find the third angle of both triangles. 

So for F the third angle for each of the pairs is
left side: 180 - (51 + 30) = 180 - 81 = 99
right side: 180 - (109 + 30) = 180 - 139 = 41
This is not the answer.

G
180 - (92 + 70) = 180 - 162 = 18
180 - (28 + 70) = 180 - 98 = 82
This is not the answer either.

H
180- (58 + 30) = 180 - (88) = 92
180 - (90  + 58) = 180 - 148 = 32
Not at all.

180 - (35 + 82) = 180 - 117 = 63
180 - (82 + 63) = 180 - 145 = 35
This pair has a third angle that is equal to the other triangle's pair. This is your answer.

In one hour Dele walks 8km. How<br> long will it take her to walk 14km at<br> the same rate?
denis-greek [22]

Answer:

1.45 h

Step-by-step explanation:

common factor of 8 and 14 is 2.

every 2km dele takes 15 minutes.

we know this because 15 minutes is 1/4 of an hour and 2km is 1/4 of 8km

14km/2km = 7

7*15 minutes = 1.45 hours

Does anyone know this answer??
Aleonysh [2.5K]

For this case we have the following equation:

(2x + 3) ^ 2 + 8 (2x + 3) + 11 = 0

Let u = 2x + 3

We have:

u ^ 2 + 8u + 11 = 0

By definition, given an equation of the form ax ^ 2 + bx + c = 0

The quadratic formula, to find the solution can be written as:

x = \frac{-b+/-\sqrt{b ^ 2-4 (a) (c)} }{2(a)}

In this case we have:

a = 1\\b = 8\\c = 11

Substituting in the quadratic formula we have:
