Answer:
13.22
Step-by-step explanation:



Note that

is defined for

, and

is defined for

, where the latter will be the "total" domain. Under this condition, you have

and

. The cosine terms can be found with Pythagoras' theorem.
So provided that

, it follows that the above reduces to

Squaring both sides gives



Squaring both sides again gives







Three of these solutions are extraneous, however.
When

, we have

.
When

, we have

.
When

, we have

.
Finally, when

, we have

, so this is our only solution.
Answer:
Wanda brought 9 carrot sticks.
Step-by-step explanation:
- Convert 30% to a decimal by removing the percent sign and dividing by 100: 30 ÷ 100 = 0.30
- Substitute 0.30 for 30% in the equation: 30% x 30 = Y becomes 0.30 * 30 = Y
- Do the math: 0.30 x 30 = 9
- Y = 9
- So 30% of 30 is 9
- Double check your answer with the original question: How many carrot sticks did Wanda bring? Multiply 0.30 x 30 = 9
Answer:
18x^2 + 12x - 6
Step-by-step explanation:
(6x - 2) (3x + 3 )
= 18x^2 + 18x -6x - 6
= 18x^2 +12x - 6
