Answer: x = 4 yd
Explanation: The base on the bottom was given (14) and the known part of the top was given (10). Subtract those two to get the length of your missing side.
What we know is 6 * 5 equals 30 so if we do 4 * 5 we get 20 as our answer
Answer:
x = 10
Step-by-step explanation:
3x + 14 + 68 = 12x - 8
Combine like terms:
3x + 82 = 12x - 8
Subtract 3x from both sides.
82 = 9x - 8
Add 8 to both sides.
90 - 9x
Now, divide both sides by nine.
x = 10
