Answer:

-45x - 18

Step-by-step explanation:

distributive property

Answer:

x = 18/45 (or, in a decimal, 0.4). Someone correct me if I'm wrong. :)

Step-by-step explanation:

We have to use the distributive property here. That means that you multiply -5x by 9 and -2 by 9. So...

9*-5x = -45x

9*-2 = -18

-45x = -18

Now, divide both sides by 45...

-45x/45 = -18/45

x = 18/45 should be the answer.

What did Matt do wrong ??

(giving the person with the most understandable answer brainliest)

Answers

He did not distribute correctly in the first step.
4(x+2)=30
4x + 8=30
He should have distributed the 4 to the 2 as well.

what is the volume of the rectangular prism​

Answers

It is all the numbers multiplied together. 135

Answer:

[tex]\Huge\boxed{D.135 cm^3}[/tex]

Step-by-step explanation:

Hello There!

We can find the volume of the figure by using the formula for volume of a rectangular prism

[tex]V=lwh[/tex]

where l = length, w = width and h = height

we are given all of the dimensions so all we have to do is plug in the values

so

V = 3 x 9 x 5

3x9=27

27x5=135

so the volume of the rectangular prism is 135 cm³

Leah's rectangular driveway is 48 feet long and 14 feet wide. With sidewalk chalk, Leah drew a straight diagonal line on her driveway from one corner to the opposite corner.

How long is the diagonal line Leah drew?

25 feet

46 feet

50 feet

62 feet

Answers

[tex]48^2+14^2=x^2\\x^2=2500\\x=50[/tex]

The length of the diagonal drawn by Leah will be 50 feets

Given the Parameters :

Length = 48 feet Width = 14 feets

The length of the diagonal is the value of the hypotenus in a right angles triangle :

Let the length of the diagonal = d

d = √(length)² + (width)²

d = √48² + 16²

d = √2304 + 256

d = √2560

d = 50.5961 feets

Therefore, the closest value for the length of the diagonal in the options given is 50 feets
