Answer:
- volume: 18 ft³
- surface area: 42 ft²
Step-by-step explanation:
The volume of a cuboid is the product of its dimensions:
V = LWH = (3 ft)(3 ft)(2 ft)
V = 18 ft³
The area is the sum of the areas of the faces. Since opposite faces have the same area, we can figure the area from ...
A = 2(LW +H(L+W)) = 2((3 ft)(3 ft) +(2 ft)(3 ft +3 ft)) = 2(9 ft² +12 ft²)
A = 42 ft²
Answer:
7½ cups of sugar
Step-by-step explanation:
2 cups of flour needs 3 cups of sugar
1 cups of flour needs 3/2=1.5 cups of sugar
1×5 cups of flour needs 1.5×5=7.5 cups of sugar=7½ cups of sugar ANS
Answer:
Infinite solutions
Step-by-step explanation:
<em><u>Distribute the 2 to (n - 1), and distribute the 2 to (3n - 1), like so:</u></em>
2(n - 1) + 4n = 2(3n - 1)
2n - 2 + 4n = 6n - 2
<em><u>Add like terms (2n and 4n):</u></em>
6n - 2 = 6n - 2
<em><u>Subtract 6n from both sides:</u></em>
-2 = -2
Since we ended up with the same term on both sides, we can't do anything else, meaning this equation has infinite solutions.
