Step-by-step explanation:

x+5=0

x= -5

(R)=P(-5)

= -5^3+2*(-5)^2-13*(-5)+10

= -125+50+65+10

= 0

Step-by-step explanation:

what the other answer tries to say is that it proves that x = -5 is a 0 point of the function P(x).

and that means that (x + 5) is a factor.

because the factors of such a polynomial are the terms of x that would bring the whole expression to 0.

so, but now to the actual division :

x³ + 2x² - 13x + 10 ÷ x + 5 = x² - 3x + 2

- x³ + 5x²

-----------------

0 - 3x² - 13x

- - 3x² - 15x

------------------------

0 2x + 10

- 2x + 10

------------------------------

0 0

as the remainder is 0, this shows that (x + 5) is a factor.

A visual-effects model maker for a movie draws a spaceship using a ratio of 1 : 24. The drawing of the spaceship is 22 inches lo
Kay [80]

Answer:

Length of spaceship in movie = 528

Step-by-step explanation:

Given that:

Drawing ratio of spaceship = 1 : 24

It means that 1 inch on drawing equals 24 inches in movie

Drawing of spaceship = 22 inches

Length of spaceship in movie = x

As the relationship is proportional,

1 : 24 :: 22 : x

Product of mean = Product of extreme

24*22 = x

x = 528

Hence,

Length of spaceship in movie = 528

oksano4ka [1.4K]

Answer:

\red{{7}^{15} }

Step-by-step explanation:

We know that,

{x}^{a}  \times  {x}^{b}  =  {x}^{a + b}  \\ ( {x}^{a} ) ^{b}  =  {x}^{ab}

Accordingly,

( {7}^{5} ) ^{3}  \\  {7}^{5 \times 3}  \\  {7}^{15}
