Hello!
We are given the equation below.
x+40=3x
We want to get all of the variables on side. First of all let's subtract 40 from both sides.
x=3x-40
Now we rearrange our equation so the commutative property will work.
x=3x+(-40)
x=-40+3x
Now we subtract 3x from both sides.
-2x=-40
We divide both sides by -2.
x=20
Our answer is A) 20.
I hope this helps!

Step-by-step explanation:
Surface area is the sum of areas of 4 triangles.
<u>Each triangle has:</u>
<u>Area of each triangle:</u>
- A = 1/2bh
- A = 1/2*9*7.79 = 35.055 ft²
<u>Surface area:</u>
- S = 4*35.055 = 140.22 ft²
Answer:
14.67
Step-by-step explanation:
area = 1/2bh therefor plug in the numbers and you get the anwser.
