How do i evaluate an expression with a given variable

Answers

To evaluate an expression with a given variable means to replace the number in the place of the variable, and then solve to find what the expression equals. 
Example would be: x + 3 and x = 4
x + 3
4+3 = 7
7 is the value of the expression now. 

How would you graph x > 5 ?

Answers

The following graph would be below!

Look at the attachment for answer.


Hi there!

First, let's look at the function x = 5: Since x = 5 is a vertical line with an x intercept of 5, without a y intercept, to graph x > 5, you would draw a dotted line in replacement of the x = 5 (since it is >, not >=) and shade in the space of the graph on the right.

Carla must ice a german chocolate cake. The diameter of the cake is 6 cm. Use the formula A = 3.14 x r2 to find the area of the cake. A) 7.07


B) 19.63
Eliminate

C) 20.56


D) 28.26

Answers

Diameter = 6    6/2 = 3
Radius = 3            3 to the power of 2 = 9
A = (3.14)(9) = 28.26
The radius(r) is half the diameter. So just plug 3 into the equation A=πr². A=3π². The area is about 29.60 (which I think you meant to write for D).

Find the factored form of 18n+12

Answers

factored: 6(3n+2)

6 is the greatest common factor of 18n and 12 so you change it to distributive property by factoring it to 6(3n+2)
if you distribute 6(3n+2) you get 18n+12
