12) the radius is 15 so with the equation (3.14)*r^2, we get (3.14)(15^2)=706.5
13) true, true (if x=4), true
14) y=0.75x+4.50, $8.25
Answer: it is A that right
Answer: x= -6 x=6
Step-by-step explanation:
expand the equation so you get (x-6)(x+6) and then set the equal to zero and solve
The answer to your question would be 150 (c)
