Hey!
Let's simplify the expression
sum = +
- The term "sum" is used when adding. Therefore, it is equal to "+".
8 times a number and 2 = 8x + 2
- 8 is equal to 8. The term "times" is used when multiplying. Therefore, it is equal to "×". "A number" is a variable. A variable can be any letter. In this case, I have made it "x", which is commonly used.
That gives you: 8x + 2

Answer:
area = 117
Step-by-step explanation:
The area (A) of a trapezoid is calculated using the formula
A = h (b₁ + b₂ )
here h = 6, b₁ = 14 and b₂ = 25
A = × 6 × (14 + 25) = 3 × 39 = 117
