Perimiter
we have a half circle and 3 sides of a rectangle
half circle
circumfernce=2pir
half of that is 1/2 2pir or pir
so
diameter=8
radius is 1/2 of that or 4
so
that arc is 4pi
the 3 sides are 8+9+9 or 26
if we use pi=3.141592
4pi+26=38.566368
rounded we get
38.57
the closest one is C
answer is C
= (x^18y^24)/(x^2y^2)
Simplified = x^16y^22
The last answer is correct (x^16y^22)
X+x²=30
x²+x-30=0
(x+6)(x-5)=0
x=-6 or x=5
