Answer:

3x-4y

Step-by-step explanation:

You need to simplify the equation. Because you can only add numbers with same variable, add 2x and x together to get 3x. Since 3x and -4y have different variables, they can't be added together, so this is the simplest form of the equation. JUST TO BE CLEAR, you won't be able to find the exact value of the variables unless you have more information. Therefore the only thing you can do is simplify.

Answer:

$h=12.5\ in$

Step-by-step explanation:

we know that

The surface area of a square prism is given by the formula

$SA=2(b^2)+4bh$

where

b is the length side of the square base

h is the height of the prism

we have

$b=5\ in\\SA=300\ in^2$

substitute

$300=2(5^2)+4(5)h$

solve for h

$300=50+20h\\20h=300-50\\20h=250\\h=12.5\ in$

Is the binomial a factor of the polynomial function? f(x)=x3+3x2−16x−48

Brilliant_brown [7]

Answer:

(x−3) no

(x+2) no

(x−4) yes

Step-by-step explanation:

Plug in the root of each binomial to see if it is also a root of f(x).

f(3) = -42

f(-2) = -12

f(4) = 0

Of the choices available, only (x−4) is a factor of f(x).

Consider the trinomial x^2 + 3x − 40. as a first step to factoring it, find the factors of −40 such that the sum of those factor

photoshop1234 [79]

What are factors of -40?
(-20)(2)
(-10)(4) (sum of these factors is 6, which is not what we wanted)
(-5)(8) = -40 and the sum of the factors (-5) and (8) is 3.

{-5, 8} is the list of factors of -40 that add up to 3.
