The area <em>A</em> of a trapezoid with height <em>h</em> and bases <em>b</em>₁ and <em>b</em>₂ is equal to the average of the bases times the height:
<em>A</em> = (<em>b</em>₁ + <em>b</em>₂) <em>h</em> / 2
We're given <em>A</em> = 864, <em>h</em> = 24, and one of the bases has length 30, so
864 = (<em>b</em>₁ + 30) 24 / 2
864 = (<em>b</em>₁ + 30) 12
864 = (<em>b</em>₁ + 30) 12
72 = <em>b</em>₁ + 30
<em>b</em>₁ = 42
Answer:
8
Step-by-step explanation:
12 times x (the first square) is equal to 16 times x-2 (the second square)
Distributed
Simplified (divided by 16)
Subtract x from both side of the equation
Both negatives cancel each other out
0.25 times what equals 2,...

What is the question you need help with?
Answer:
P = 20.
Step-by-step explanation:
Given that:
the variable that is not given is P. So to find out P, we substitute the two given values into the equation as following:
P= 2L + 2W
<=> P = 2(6) + 2(4)
<=> P = 12 + 8
<=> P = 20.
Hope it will find you well.
