Answer:
The answer to your question is the letter A) 470 u²
Step-by-step explanation:
Data
HJ = 32
KL = 15
height = 20
Formula
Area of a trapezoid = (long base + small base) height / 2
Substitution
Area of a trapezoid = (32 + 15)20/2
Simplification
Area of a trapezoid = (47)(10)
Result
Area of a trapezoid = 470 u²

Step-by-step explanation:
Answer:
x = the flat fee = $1.5
y = fee per each letter sent = $0.7
Step-by-step explanation:
Let
x = the flat fee
y = fee per each letter sent
The equations
x + 35y = 26 (1)
x + 18y = 14.10 (2)
Subtract (2) from (1) to eliminate x
35y - 18y = 26 - 14.10
17y = 11.9
y = 11.9/17
y = 0.7
Substitute y = 0.7 into (1)
x + 35y = 26 (1)
x + 35(0.7) = 26
x + 24.5 = 26
x = 26 - 24.5
x = 1.5
x = the flat fee = $1.5
y = fee per each letter sent = $0.7
I think A is 15.25
I think B is 832
I hope its right
