Answer:
a candy is $4
you have a $20 bill
1 candy = 4
2 candies = 8
3 candies = 12
4 candies = 16
5 candies = 20
you can buy 5 candies for $20.
Answer:
I think the third one.
Step-by-step explanation:
The surface area of a sphere is

where r is the radius;
The circumference is

so that

using this value we can evaluate the surface area of 1 ball as:

For 100 ball you get:
<span>Part A: Area = length * width = (6x^2 + 3x - 2) * (x^3 - 2x + 5)
Multiply it out and simplify.
part B: </span><span>Take the first term 6x^2 and multiply each of the term x^3, -2x & 5. Then take 3x and multiply each of the term x^3, -2x & 5. Do the same with -2.
Then add like terms and simplify.</span>
