Answer:
8b + 9x + 16
Explanation:
Hello!
To find the perimeter, add up all the measures of the sides, and combine like terms.
Like terms are terms in which the variables and exponents are the same. You combine their coefficients to find the value.
Ex:
- 3x + 2x + 4 + 2 (3x and 2x are like, and 4 and 2 are like)
- (3 + 2)(x) + (4 + 2)
- 5x + 6
Find the Perimeter
- (4b + 2) + (4b + 2) + (3x + 4) + (3x + 4) + (3x + 4)
- 4b + 4b + 3x + 3x + 3x + 2 + 2 + 4 + 4 + 4 (Combine like terms)
- 8b + 9x + 16
The perimeter is 8b + 9x + 16.
