No, they are not equivalent.

5(2x - y) = 10x - 5y and it is not equal to 15x - 5y.

(using distribution property)

A right rectangular prism has length 3 and one third yd​, width 2 and one third yd​, and height 1 and one third yd. You use cube
Levart [38]

Answer:

Volume of the rectangular prism = 280 cubes

Volume of the rectangular prism = (280/27) yd³

Step-by-step explanation:

length 3 and one third yd​ = 3 + (1/3) yd = (10/3) yd

width 2 and one third yd​ = 2 + (1/3) yd = (7/3) yd

height 1 and one third yd = 1 + (1/3) yd = (4/3) yd

Cubes of edge length (1/3) yd are used to fill the rectangular prism.

The length would contain (10/3) ÷ (1/3) = 10

The width would contain (7/3) ÷ (1/3) = 7

The height would contain (4/3) ÷ (1/3) = 4

Volume of the rectangular prism = 10×7×4 = 280 cubes

Or

Volume of rectangular prism = (10/3)(7/3)(4/3) = (280/27) yd³

What is the sum of the measures of interior angles ofna regular polygon if each exterior angle measures 72°?
WARRIOR [948]
We know that

The exterior angle measures of a polygon must add up to 360°, 

therefore

 360°/72°=5 exterior angles

so

5 exterior angles, would mean 5 interior angles and therefore  5 sides to the polygon

The exterior angle and the interior angle of any polygon are supplementary and must add up to 180°.

exterior angle+interior angle=180°

interior angle=180°-exterior angle

interior angle=180°−72°-------> 108°
Each interior angle is 108°

The sum of the interior angles would be 

5*108°=540°

the answer is

540°

Evaluate each expression if w=2, x=3, y=5, and z=6. 3+4z
SashulF [63]

Answer:

27

Step-by-step explanation:

The expression is 3 + 4z

First, you must know what the value of the variable "z" is.

Because the problem already tells you that z = 6, all you have to do is substitute z with 4:

3 + 4z = 3 + 4(6)

Next, solve using the Order of Operations (P.E.M.D.A.S.).

According to the Order of Operations, multiplication (M) comes before Addition (A). That means you must multiply 4 by 6 first then add the product to 3:

3 + 4(6) = 3 + 24 = <u>27</u>
