Answer:
x = 8
Step-by-step explanation:
-4x + 6(6 - 2x) = -7x - 36
-4x + 36 - 12x = -7x - 36
-16x + 36 = -7x - 36
<u> +36 +36</u>
-16x + 72 = -7x
<u>+16x +16x</u>
72 = 9x
divide by 9
<u><em>x = 8</em></u>
Answer:
390625
Step-by-step explanation:
The questions are all independent -- the answer on one question does not limit the number of possible answers on another question.
The quiz has 5 choices for each question, so there are
ways to answer the quiz questions.
Notice that this could be written
. You could say that the number of ways to answer the questions is
![number \, of \, choices^{number \, of \, questions}](https://tex.z-dn.net/?f=number%20%5C%2C%20of%20%5C%2C%20choices%5E%7Bnumber%20%5C%2C%20of%20%5C%2C%20questions%7D)

![\frac{824}{tan\left(23\right)}](https://tex.z-dn.net/?f=%5Cfrac%7B824%7D%7Btan%5Cleft%2823%5Cright%29%7D)
Convenience sample because it was easier for the researcher to go to.
A = (1/2)bh [b = 10 m, h = 6 m]
A = (1/2) * 10 * 6 = 30 m²
