Answer:
C and E
Step-by-step explanation:
Examples of binomials (two terms) :
9a - 5
3x + 6y
-4t + 2
Examples of monomials (one term) :
6x
10z
4a
Examples of trinomials (three terms) :
7y - 3x + 4
8x + 7 - 2a
4x + 9y + 5
(There can also be exponents and fractions in any kind: binomial, monomial, or trinomial.)
L = 2 W
B = L x W = 2 W²
Side Area = 2 W H + 2 L H = 2 H ( W + L ) = 6 H W
V = 2 W² H = 10
H = 5 / W²
Cost = 15 * 2 W² + 9 * 5/W
= 30 W² + 270/ W
C ` = 60 W - 270 / W²
= ( 60 W² - 270 ) / W² = 0
60 W² = 270
W ² = 270 : 60
W² = 4.5
W = √ 4.5 = 2.12
Cost (min) = 15 * 2 * 4.5 + 30 / 2.12 = 135 + 14.15 = $149.15
Answer: The cost of materials for the cheapest such container is $149.15.
