Answer: 88 inches
Step-by-step explanation:
A bicycle tire is 28 inches in diameter. approximately.
To find the distance traveled by the bicycle each time the wheel goes around we need to find the circumference of the tire.
The circumference of a circle: where d is the diameter of the circle.
Now, the circumference of the tire:
Hence, the distance traveled by the bicycle each time the wheel goes around =88 inches.
Answer:
8x³ - 25x² - 3x + 18
Step-by-step explanation:
(2x + 3)(4x²- 5x + 6)
multiply 2x by each of the three terms in the second expression to get:
8x³ - 10x² + 12x
now multiply 3 by each of the three terms in the second expression to get:
12x² - 15x + 18
Combine 'like terms': -10x² + (-15x²) = -25x²
Combine 'like terms': 12x + (-15x) = -3x
Put all terms in decreasing exponent order:
8x³ - 25x² - 3x + 18
Answer:
Height = 20, Base = 6
Step-by-step explanation:
The area of a triangle is 
where b is the base and h is the height
We can factor by grouping
Length can only be positive, so we know that the base is 6 in
The height must be 2 + 3(6) = 20
Height = 20, Base = 6
