Answer:
h = 4
Step-by-step explanation:
The area (A) of a trapezoid is calculated as
A = 
h( a + b) ← a and b are the parallel bases
here a = 5, b = 8 and A = 26, thus
h(5 + 8) = 26, that is
h × 13 = 26 ( divide both sides by 13 )
h = 2 ( multiply both sides by 2 to clear the fraction )
h = 4
The way I am reading this is 16=(x/3)-8. In that case, x=72. I hope that's the right way of interpreting this :)
5a^2 - 6a -4 - (<span>-7a^2 + 3a -9)
=</span>5a^2 - 6a -4 + 7a^2 - 3a + 9
=12a^2 - 9a + 5
answer
12a^2 - 9a + 5
Using complementary events, considering a 
probability of drawing a red marble, the probability of not drawing a red marble is of 
.
<h3>What are complementary events?</h3>
They are mutually exclusive events which have the sum of their probabilities as 1.
In this problem, we consider that there is a probability of drawing a red marble, and since drawing a red marble and drawing a non-red marble are complementary events, we have that:
The probability of not drawing a red marble is of .
