Answer:

Option 1 - Division Property of Equality

Step-by-step explanation:

Given : If  4x=20, then x=5.

To find : Which property justifies this statement?

Solution :

The equation is  4x=20

To make variable separate we have to remove 4 which is in multiple of variable x.

So, We divide both side by 4,

Applying division property of equality,

We can divide both sides of an equation by the same number and preserve equality.

\frac{4x}{4}=\frac{20}{4}

x=5

Therefore, The property justifies the statement is 'Division Property of Equality'.

So, Option 1 is correct.

a rectangular prism is 5 meters long, 17 meters wide, and 4 meters high. what is the surface area of the rectangular prism?
Mars2501 [29]

The surface area of rectangular prism is 346 square meters.

Given the figure is rectangular prism.

We know that the surface area of rectangular prism with length L, width W and height H is = 2(LW+WH+LH)

Given that the length of prism = 5 m

Width of prism = 17 m

Height of prism = 4 m

So the total surface area of the rectangular prism is given by,

= 2 [5*17 + 17*4 + 4*5]

= 2 [85 + 68 + 20]

= 2*173

= 346 square meters

Hence the surface area of rectangular prism is 346 square meters.

KonstantinChe [14]
<h3>Answer: Choice C</h3>

================================================

Work Shown:

Reference angle = P

Opposite side = QR = 8.5

Adjacent side = QP = 16

tan(angle) = opposite/adjacent

tan(P) = QR/QP

tan(P) = 8.5/16

tan(P) = 0.53125

tan(P) = 0.53

A prime number being a number with only 2 factors.That is 1 and the number itself.

For example 5 only has 2 factors 1 and 5⇒5=1×5

Here are the first few prime numbers

2,3,5,7,11,13,.....

A number which is not prime is a composite number. Composite numbers have more than 2 factors. All composite numbers can be expressed as a product of prime factors.
