By adding 3 to both sides and dividing both sides of the equation by 4 you end up with x=6
answer is x =6
Hope this helps!!
It is a right triangle so,
a² + b² = x²
9² + 12² = x²
225 = x²
√225 = x
15 = x
Hope this helps :)
Rectangle on top is 4 units by 8 units = 32 units squared.
The half circle has radius 2, so the area is pi*2^2/2 = 4pi /2 = 2pi
Total area is 32+2pi or approx 38.28 square units, answer C
