The exclamation points mean factorial which is when you multiply that number along with the numbers less than it. Ex: 4! = 4*3*2*1. To solve this, you must get those factorials and after you solve, you get 60480
SinC=(8/17)
solve for C = arcsin(8/17)
Answer:
She forgot to flip the inequality sign when dividing both sides by -4
5*4*6=120
4+(6+9)=19
675+9=75
This is simple:
area= Length x Width
