Answer:

4(3 +20)

Step-by-step explanation:

12 = 4·3

80 = 4·20

The greatest common factor is 4, so the factorization can be ...

12 +80 = 4(3 +20)

P(x)=2x^5+9x^4+9x^3+3x^2+7x-6;x=i,-2

satela [25.4K]

Answer:

The value of the polynomial function at P(1) and P(-2) is 24 and 0 respectively.

Step-by-step explanation:

We are given with the following polynomial function below;

$\text{P}(x) = 2x^{5} +9x^{4} +9x^{3} +3x^{2}+7x-6$

Now, we have to calculate the value of P(x) at x = 1 and x = -2.

For this, we will substitute the value of x in the given polynomial and find it's value.

$\text{P}(1) = 2(1)^{5} +9(1)^{4} +9(1)^{3} +3(1)^{2}+7(1)-6$

$\text{P}(1) = (2\times 1) +(9\times 1)+(9 \times 1)+(3\times 1)+(7\times 1)-6$

$\text{P}(1) = 2 +9+9+3+7-6$

P(1) = 30 - 6

P(1) = 24

$\text{P}(-2) = 2(-2)^{5} +9(-2)^{4} +9(-2)^{3} +3(-2)^{2}+7(-2)-6$

$\text{P}(-2) = (2\times -32) +(9\times 16)+(9 \times -8)+(3\times 4)+(7\times -2)-6$

$\text{P}(-2) = -64 +144-72+12-14-6$

P(-2) = 156 - 156

P(-2) = 0

Hence, the value of the polynomial function at P(1) and P(-2) is 24 and 0 respectively.

PLEASE HELP ASAP

qwelly [4]

Answer: In the expression , $x^2+15x$

The area of the photo = $x^2$ ( the second degree term, of the expression $x^2+15x$ )

The area of the frame around the picture = 15x ( the first degree term of the expression )

The length of the frame = x + 15 cm, ( the binomial, (x+15), a factor of expression $x^2+15x$ )

The length of the photo = x, ( the monomial, x, a factor of expression $x^2+15x$ )

Step-by-step explanation:

Here x represents the length of the photo,

While the length of the frame is 15 more than that of photo,

⇒ Length of the frame = (x+15) cm,

Since, the photo is of square shape,

⇒ Area of the photo = $x^2$ square cm

Also, the breadth of the frame = x cm,

And, frame is of rectangular shape,

⇒ Area of the frame = (x+15)×x = $x^2+15x$ square cm

Also, the length of the fram around the picture = 15 cm

And, the breadth of that area = x cm

⇒ The area of the frame around the picture = 15x square cm

Order the events from least likely (on top) to most likely (on bottom).

Aneli [31]

Answer:

so, look at the percentage, since -20 is lower, it is least likely, next is 10%, next s the 30% and last, the 4/5th. 4/5 simplified is 80% or 80 out of 100
