12 out of 18. This is because there is 6 red marbles and 18 of them all together. The question states the probability of the red marble NOT being chosen therefore you need to take away 6 from 18 leaving you with 12. I hope this made sense :)
Yup I can! (For the third time ;) )
This one was a bit tricky for me, So I am 90% sure ;)
Answer: 336pi in^2
Explanation: The explanation is quite long, so I won't go into much detail :) Just keep the formula in mind!! :>
If available please give me a Branliest. It would be much appreciated.

We know that A. ∠ADE 
∠ABE because those are the only angles involved with

Answer:
1 and -2 (has a multiplicity of 2)
Step-by-step explanation:
so since x=-2 is a root then (x+2) is a factor of the polynomial. This means you can divide the polynomial by (x+2) by using synthetic or long division. So for this example I'll using synthetic division which is much more simple than long division
-2 | 1 3 0 -4
-2 -2 4
1 1 -2 0
(x+2)(x²+x-2)
Now you can factor the quadratic into
(x+2)(x-1)
x+2 = 0
x = - 2
x-1 =0
x = 1
Answer:
SA = 299600 m²
Step-by-step explanation:
Equation for the surface area of a prism:
SA = 2 * Area of base + Perimeter of base * height
1. Perimeter of the base: 280 * 5 = 1400 m
2. Area of the base: 0.5 * apothem * perimeter -> 0.5 * 192 * 1400 = 134400 m²
Plug in: SA = 2 * 134400 + 1400 * 22 -> SA = 268800 + 30800 ->
SA = 299600 m²
