Answer:
a. 2x + 30
Step-by-step explanation:
The perimeter of a rectangle is represented by
2l + 2w
So substitute the rectangle values into the equation.
2(2/3(x) + 10) + 2(1/3(x) + 5)
Rewrite fractions for clarity.
2(2x/3 + 10) + 2(x/3 + 5)
Distribute the two into the first expression.
4x/3 + 20 + 2(x/3 + 5)
Distribute the two into the second expression.
4x/3 + 20 + 2x/3 + 10
Combine like terms.
6x/3 + 30
Simplify 6x/3.
2x + 30.

Answer: 8a + 7b + 2c</h3>
Work Shown:
(11a - 2b + 7c) - (3a - 9b + 5c)
11a - 2b + 7c - 3a + 9b - 5c ... see note below
(11a-3a) + (-2b+9b) + (7c-5c)
8a + 7b + 2c
note: don't forget to distribute the negative through to every term inside the parenthesis
