Step-by-step explanation:
The top and bottom triangles have two congruent sides with different included angles.
- AB = AD and AC is common side.
<u>The greater angle has greater op</u>posite side.
- The ∠BAC is greater than the ∠DAC as opposite side of the first (22) is greater than the opposite side of the second (16).
The ∠DAC must be greater than zero but smaller than 48°.
<u>Required inequality is:
</u>
- 0 < 2x - 12 < 48
- 12 < 2x < 60
- 6 < x < 30
So x has a value between 6 and 30
Answer:
(B) The exponents should be subtracted by the quotient rule of exponents
Step-by-step explanation:
Let's examine how this was solved.
He first rose everything in the parentheses to the second power, which is just multiplying all the exponents by 2. This is correct.
He then combined the numerator exponents. Exponent rules say that 
, so he should have ended up with 
, which he did. This is correct.
Now, what he did in the final step is wrong. He added the exponents. However, exponent rules tell us that when we have 
, it equals 
.
So the final answer should have been

The word mean is a synonym for average. To find the average, you add all of the data, then divide by the amount of data received.
So, we add 2+4+3+5+4+6+5+3+6+3+7+0+8+1. That totals to 57. Then, we divide by 14 because there are 14 answers. The end result is 4.07, because we round up.
