Answer:
<h2>A = 82.5 in²</h2>
Step-by-step explanation:
The formula of an area of a trapezoid:

b₁, b₂ - bases
h - height
We have b₁ = 10in, b₂ = 5in and h = 11in. Substitute:

(50/4) + (6/4) is the answer that you are looking for. All you do is break up the number that you are going to divide into easy-to-divide numbers.
Answer:
86 °F = 30 °C
Step-by-step explanation:
Put the given number in the equation and solve for C.
86 = 9/5C +32
54 = 9/5C
(5/9)54 = C = 30
The equivalent is 30 degrees Celsius.
