Answer:
-6w-22
Step-by-step explanation:
-3(2w+6)-4=
= -6w-18-4=
= -6w-22
So,choose C (none of the above) :)
Answer:
For number 5 is n=10
Step-by-step explanation:
Answer: 
Step-by-step explanation:

We need;

We don't have the radius, but we do have the diameter. A diameter is twice the radius. Therefore, we can divide the diameter by 2 in order to obtain the radius.

Now plug this info into the formula.
![(3.14)(12yd)[(12yd)+\sqrt{(18yd)^2+(12yd)^2} ]](https://tex.z-dn.net/?f=%283.14%29%2812yd%29%5B%2812yd%29%2B%5Csqrt%7B%2818yd%29%5E2%2B%2812yd%29%5E2%7D%20%5D)
Let's solve the square root first.
![(3.14)(12yd)[(12yd)+\sqrt{324yd^2+144yd^2} ]](https://tex.z-dn.net/?f=%283.14%29%2812yd%29%5B%2812yd%29%2B%5Csqrt%7B324yd%5E2%2B144yd%5E2%7D%20%5D)
![(3.14)(12yd)[(12yd)+\sqrt{468yd^2} ]](https://tex.z-dn.net/?f=%283.14%29%2812yd%29%5B%2812yd%29%2B%5Csqrt%7B468yd%5E2%7D%20%5D)
![(3.14)(12yd)[(12yd)+\sqrt{468yd^2} ]\\(3.14)(12yd)(12yd+21.63yd)](https://tex.z-dn.net/?f=%283.14%29%2812yd%29%5B%2812yd%29%2B%5Csqrt%7B468yd%5E2%7D%20%5D%5C%5C%283.14%29%2812yd%29%2812yd%2B21.63yd%29)
Now solve the sum

Multiply

To calculate expected value,
We can add up the probability of all possible events.
The 2 possible events are either winning $50 or losing the prize, which is $ - 50
Expected value =
50 x 40 % + (-50) x 60%
= $-10
So the answer is $-10
Answer:
y=4x-2
Step-by-step explanation:
if slope is 4, gradient is 4 so y=4x +c
given y intercept of -2,, y=4x -2
c=-2
