Answer:

Step-by-step explanation:

A is not, because 2-5x = -5x+2

(nothing has changed but the order)

B is not, because 3-5+2x = 2x-2

because 3-5 = -2. so -2+2x can be rewritten as 2x-2.

C is not, because 5x-2x = 3x

because you combine like terms, and 5-2 is 3

D is, because 2x-2+3x = 5x-2

because you combine like terms (2x+3x=5x) and -2 is left.

Super confused definitely need help on this

Answer:

$(x-5)(x+8)=x^2+3x-40$

Step-by-step explanation:

So we have the expression:

$(x-5)(x+8)$

To multiply, distribute the left to the terms on the right:

$=(x-5)(x)+(x-5)(8)$

Distribute:

$=(x^2-5x)+(8x-40)$

Combine like terms:

$=(x^2)+(-5x+8x)+(-40)$

Simplify:

$=x^2+3x-40$

Therefore:

$(x-5)(x+8)=x^2+3x-40$

Find the distance between the points (-9,0) and (2,5)

andreev551 [17]

Answer:

sqrt(146)

Step-by-step explanation:

The distance between these two points can be the hypotenuse of our right triangle.

We can create a right triangle with two legs of length 11 and 5. To solve for the hypotenuse, we apply the pythagorean theorem

sqrt(5^2+11^2)=sqrt(146)

I attached a graph to help you visualize the triangle and how it works.
