Answer:
D
Explanation:
add all the know sides 8+8+3+5=24
perimeter of half a semicircle=circumference of half a semicircle
if circle is C=π×d
than semi C=1/2×d×π
C=½×4×π
C=2pi
so 24+2pi
Answer:
B. -3
Explanation:
Our equation is:
. We see that both sides have a term with denominator ax - 2, so let's add
to both sides:



Now multiply both sides by ax - 2:


We essentially want to make the terms on each side match. Look at the coefficient of x² on the left side: it's 24. That means on the right side, it should be 24, as well. Then, set -8a equal to 24:
-8a = 24
a = -3
Thus, the answer is B.
