A difference of 1 foot and the shorter fence is 2 feet high so the taller fence is 2+1 = 3 feet tall
Answer: <em>A = -14</em>
Step-by-step explanation:
<em>First, remove the parentheses</em>
<em>8(3a+6) =9(2a-4)</em>
<u><em>24a+48=9(2a-4)</em></u>
<em>Move the terms</em>
<em>24a+48=18a-36</em>
<u><em>24a-18a+48=-36</em></u>
<em>Collect the like terms (Calculate)</em>
<em>24a-18a=-36-48</em>
<u><em>6a=-36-48</em></u>
<em>Divide by both sides</em>
<em>6a=-84</em>
<em>Solution: a=-14</em>
<u><em /></u>

Step-by-step explanation:
Answer:
Step-by-step explanation:
y+3=2(x-9)
The vector equation of the line through the origin perpendicular to the plane is
.. (x, y, z) = t(2, 3, -1)
so the point of interest will satisfy
.. 2(2t) +3(3t) -(-t) = -3
.. 14t = -3
.. t = -3/14
and its coordinates are (x, y, z) = (-3/7, -9/14, 3/14)
