Answer:
incenter
Step-by-step explanation:
From what I think;
8.216secs - 1 wheel; 3.652- 1 hood
for I toy car with a wheel and hood the total time is 8.216+ 3.652 = 11.868secs
let x secs be the total time taken to put a wheel and hood for 42 cars
x secs = 42 cars × the total time for one car
x secs = 42× 11.868
x secs= 498.456 secs
Answer: 1.5
Step-by-step explanation:
The roots are just the zero value of the formula. To find these, we factor:
(x - 2)(x - 2)
(x - 2)^2
to make this into a zero, we set x-2 = 0, then solve for x
x = 2
If x = 2, then the brackets = 0, and those are the roots
The roots are x = 2
