Since W and V and X and U are congruent, or symmetrical to eachother, they equal eachother. 7 is x+1. So, x=6.
Answer: I'm pretty sure its 12
Step-by-step explanation: You count the unit length of the base and then find the height. Now you multiply them and divide by 2.
Hope this helps.
Branliest please
Step-by-step explanation:
To find the perimeter of something, we add all of the measurements of the sides together.
A rectangle has 4 sides, this means we must double the algebraic hints given to us.
If we add them all up together it will look like this:
x-9+x-9+3x-4+3x-4=138
If we simplify it by collecting the like terms:
8x-26=138
We add 26 onto 138
8x=164
To find out what x equals, we divide by 8:
164÷8= 20.5
Answer:
x=20.5cm
x-9 is 11.5
3x-4 is 57.5
I know that you will not give 100 points but just wanted to help.
Hi there!
Let's solve this inequality step by step!

First collect the terms on the left.

In order to solve, we must isolate r. Therefore we need to bring them all to the left. Our next step will therefore be to add 3r to both sides of the equation.

Finally we need to divide both sides of the equation by -1. Because we divide by a negative, the sign flips.

Hence, the answer is r < -3.

When writing an expression in expanded form, we just need to multiply what's outside the parentheses by everything that is inside the parentheses.
5a (6b + 12)
(5a * 6b) + (5a * 12)
30ab + 60a
And that is our answer.
5a (6b + 12) in expanded form is 30ab + 60a.
Hope that helped =)
