Step-by-step explanation:
We are given that ,
The equation
represents the total cost of buying buying carnival tickets , where x= Number of carnival tickets and y= Total cost.
To find : The cost of 15 carnival tickets.
In the given equation , we substitute the value of x = 15 we get
Thus , According to the equation, the total cost of 15 carnival tickets= $ 37.50
Hence , the correct answer is $ 37.50 .

Step-by-step explanation:
Answer:
D.
Step-by-step explanation:
Complementary angles are two angles whose measures add to 90°.
A.
m<CFD = 150° - 100° = 50°
m<EFD = 180° - 150° = 30°
Sum = 80°
No
B.
m<AFB = 40°
m<DFE = m<EFD = 30°
Sum = 70°
No
C.
m<AFC = 100°
Sum > 100°
No
D.
m<BFC = 100° - 40° = 60°
m<DFE = 30°
Sum = 90°
Yes
Answer: D.
So for this trinomial, I will be factoring by grouping. Firstly, what two terms have a product of 16x^2 and a sum of 10x? That would be 8x and 2x. Replace 10x with 2x + 8x:

Next, factor x^2 + 2x and 8x + 16 separately. Make sure that they have the same quantity inside the parentheses: 
<u>Now you can rewrite this as
, which is your final answer.</u>
