3b because b^2-4= 1/b. So 2/1/b= 2b b+2b = 3b
Answer:
Triangle C
Step-by-step explanation:
Triangle C contains a 90° angle.
Answer:
9x/4= -9
Mutiply by 4 for both sides.
4(9x/4) cross out 4 and 4, divide by 4 and then becomes 9x. (-9)(4)= -36
9x= -36
Divide by 9 for both sides
9x/9= -36/9
x= -4
It would be 18.37 because 4 is smaller then 5, so you round down.
I guess you're supposed to simplify?
