The answer is B. 8x+6. You multiple 3 and x+4 then combine like terms
Answer:
125 - 12 /3 = 125 - 4 = 121
Step-by-step explanation:
Answer:
504 km
Step-by-step explanation:
divide 180 by 15 (because 3 hours is 180 minutes)
after you divide you get 12
then multiply 12 by the 42 kilometers and you get 504
Answer:
a
Step-by-step explanation:
A is the answer, since when you graph it, you are able to visualize y crossing -2 and x crossing 3.
Answer:
5 inches
Step-by-step explanation:
The volume of a cone formula is V = (1/3)(base)(height). Thus, 3V =(base)(ht).
We want to calculate the height of the cone. Divide both sides of
3V =(base)(ht) by (base), obtaining 3V/(base) = ht.
Substituting 12 in^3 for V, and 2.25pi for (base), we get:
12 in^3
------------ = 5.33 in, or, to the nearest inch, 5 inches.
2.25 pi
Note: The diameter of the cone is 3 inches. The area of the base is pi*r^2, so we must divide d = 3 inches by 2 to obtain the radius: 1.5 in. Then r^2 = 2.25 in^2.
