Answer:
x³ + 5x² + 5x - 2
Step-by-step explanation:
Given
x³ + 3x² - x + 2x² + 6x - 2 ← collect like terms
= x³ + (3x² + 2x² ) + (- x + 6x ) - 2
= x³ + 5x² + 5x - 2
Answer:
Just took it!
Step-by-step explanation:
Answer:
.
Step-by-step explanation:
is the equation for a circle with center (h,k) and radius r.
You are given center (6,2) and radius 4.
So we will replace h with 6 and k with 2 and r with 4.
This gives us:

Simplify:
.
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
