Let x = the width
then
2x = the length
:
The box dimensions: 2x by x by 4
Given the surface area:
2(2x*x) + 2(2x*4) + 2(x*4) = 220
:
4x^2 + 16x + 8x = 220
A quadratic equation:
4x^2 + 24x - 220 = 0
simplify, divide by 4
x^2 + 6x - 55 = 0
Factor
(x+11)(x-5) = 0
The positive solution is what we want here:
x = 5 ft is the width
then
2(5) = 10 ft is the length
:
Find the volume
10 * 5 * 4 = 200 cu/ft is the volume
I think the answer is A.
It's probably wanting you to use pythagorean theorem.
Answer:
C: mean 6.5 median 6
Step-by-step explanation:
median you find middle number in sorted numbers lined up. mean is all numbers added up and divided by how many there are
1
(a) The total cost, C, is given by:
b) With 3 ounces of toppings, we have
Hence Evan's ice cream would cost $4.50
