A. 12x+y=6<span>B. −2x+y=6</span>
Answer:
12 inches
Step-by-step explanation:
The formula for a trapezoid is
A = 1/2(a +b)h
The formula to find the height =
h = 2A/a + b
A= 216 in²
a =14 in
b = 22 in
Hence,
h = 2 × 216/14 + 22
h = 12 inches
The height of the trapezoid = 12 inches

Answer:
<u>x = 14</u>
Step-by-step explanation:
4x + (2x + 6) = 90
6x + 6 = 90
subtract both sides by 6:
6x + 6 <em>- 6 </em>=<em> </em>90 <em>- 6</em>
6x = 84
divide both sides by 6
6x/6 = 84/6
x = 14
double check:
4*14 + (2*14 + 6) = 90
56 + 28 + 6 = 90
Have a nice day!
