Answer:
x = 6
Step-by-step explanation:
Givens
There are 3 sides. All are equal to (4x - 3)
Their sum = 63
Formula
3(4x - 3) = 63
Solution
- 3(4x - 3) = 63 Divide by 3
- 12x - 9 = 63 Add 9 to both sides
- 12x = 63 + 9
- 12x = 72 Divide by 12
- x = 72/12
x = 6 Answer
5x - 20 = 8x - 65
-20 = 3x - 65
3x = 45
x = 15
Answer:
Yes
Step-by-step explanation:
Well let's solve it!
In order to solve this, plug in x into the equation.
Let's do the side on the LEFT of the equal sign first.
3(3+1) = 3(4) = 12
Now Let's do the side on the RIGHT of the equal sign.
3(3) + 3 = 9+3 = 12
So this means they are equal or congruent!
