Answer: B
Step-by-step explanation: All you have to do is plug in the numbers and solve the equation. B is not correct, because 35+40(9) is not equal to 355.
Answer:
10
Step-by-step explanation:
We can use the distributive property to get:

Therefore, the blank is 10.
The base of a cone is a circle.
The area of a circle is

.
Thus, the area of the base of a cone

.
The derivation of the formula for the area of a circle involves a bit of calculus, but if you'd like, I can walk you through it.
Answer:
Endpoint at one end and an arrow at the other end.
Step-by-step explanation:
Answer:
y = 4x + 5.5
Step-by-step explanation:
We put 2y in the y spot, obviously
2y = mx + b
Then we put 8x in the x spot
2y = 8x + b
Then we put 11 in the b spot
2y = 8x + 11
Then, to simplify, we divided by equation by two (it still gives the same results)
y = 4x + 5.5
