Because u just put the 2.11 in that order
If the perimeter is known / given and is 6x, you can find the length of the unknown side by adding up the lengths of the other two sides and subtracting this sum from 6x:
6x - (x+3 + 2x + 4) = 6x - x - 3 - 2x - 4
Combining like terms, 3x - 7 represents the length of the unknown 3rd side.<span />
Answer:
x = 26
Step-by-step explanation:
There are two numbers and average is the sum of a certain amount of numbers divided by the same amount.
21 × 2 = 42
42 - 16 = 26
x = 26
