Answer:
You add the exponents keeping the base.
Step-by-step explanation:
The exponent "product rule" tells us that, when multiplying two powers that have the same base, you can add the exponents.
For example:
4^2 x 4^18
= 4^(2+18)
= 4^20

Answer: D. Getting at least 2 heads and Getting at least 2 tails
=========================================================
Explanation:
Choice A is not disjoint because "getting at least 1 tail" could have the sequence TTH. We see that we have two tails and exactly one head. So the events "getting exactly 1 head" and "Getting at least 1 tail" are possible to occur at the same time; therefore, they aren't disjoint events. Disjoint events are two events that cannot occur simultaneously. An example would be flipping heads and tails on the same coin at the same time.
Choice B is also not disjoint. We could have the sequence THT, which has at least one head and at least one tail. "At least" means that amount or more.
Choice C is also not disjoint. We could have the sequence HTT. This has exactly one head and at least two tails.
Choice D is the only thing left. It must be the answer. It is not possible to get 2 heads and 2 tails when Roger only flips the coin 3 times. He would need to flip the coin at least 4 times for this to happen. The portions "at least" don't even need to be considered. So this shows how choice D is disjoint.
a. Surface area = 172 cm²
Volume = 112 cm²
b. The surface area would be needed.
c. The volume would be needed.
<h3>How to Find the Surface Area and Volume of a Box?</h3>
Surface area = 2(wl+hl+hw).
Volume = (length)(width)(height)
a. l = 7 cm
w = 2 cm
h = 8 cm
Surface area =2(wl+hl+hw) = 2·(2·7+8·7+8·2) = 172 cm²
Volume = (7)(2)(8) = 112 cm²
b. The surface area would be needed.
c. The volume would be needed to find the amount of juice the box will hold.

The y-intercept would be (0,-3) and the x-intercept would be (-6,0).
So, first you need to think 'what is the highest degree?'
Then you need to figure out how many terms you have
polynomial- four or more terms
trinomial- three terms
binomial- two terms
