The cost of the visit to the dentist can be expressed as the cost equals 100x+50.
The initial cost of the appointment would be $50; no matter how many cavities one has, they would still have to pay $50.
The cost of each cavity is represented as 100x, because each cavity costs $100. x represents the number of cavities, as we do not know how many cavities there are.
Answer:
B. 7x - 5
Explanation
Given the expression 21x^2 + 13x – 20, to get which of the given expression is a factor we will have to factorize the equation first as shown;
21x^2 + 13x – 20
= 21x^2 + 28x - 15x - 20
= 7x(3x+4) -5(3x+4)
= (7x-5)(3x+4)
Hence one of the factors is 7x - 5
20in flat -> 2 sides of 10in at 90degrees from eachother
area would be 10*10/2 =50in^2
Answer:

Step-by-step explanation:
Answer:
12.6 cm
Step-by-step explanation:
Given:
m<AOB = θ = 120°
Diameter (d) = 12 cm
Required:
Length of arc AB
Solution:
Length of arc AB = θ/360 × πd
Plug in the values
Length of arc AB = 120/360 × π×12
≈ 12.6 cm (nearest tenth)
