Answer:
V = x³ + 3x² + 3x + 1 in³
Step-by-step explanation:
The volume (V) of a cube is calculated as
V = s³ ( where s is the side ) , then
V = (x + 1)³
= (x + 1)(x + 1)(x + 1) ← expand second pair using FOIL
= (x + 1)(x² + 2x + 1) ← distribute
= x³ + 2x² + x + x² + 2x + 1 ← collect like terms
= x³ + 3x² + 3x + 1

Sarah bought 18 boxes of 65 pens at $12 a box. She sold 378 of them at 3 for $1.00 and the rest at 4 for $1.00. Find her total profit.
Answer:
$108
Step-by-step explanation:
1 box = $12
18 boxes = 12×18 = $216
Total = 18×65 = 1170 pens
Cost price, Cp = $216
3 = $1
378 = 378/3 = $126
1170-378= 792 pens remaining
4 = $1
792 = 792/4 = $198
Total selling price, sp = 126+198 = $324
Profit = Sp - Cp = 324 - 216 = $108
Mrs. Mobley can jog 3 miles in 27 minutes. How many miles can she jog in 81 minutes?
Answer:
9 miles
Step-by-step explanation:
You need to get 27 minutes to 81 minutes so you multiply 27 by 3, and that is 81, so you simply multiply 3 by 3 and get 9! Hope this helps! ;)
(27 x 3) = 81
(3 x3) = 9
Carla packed this box with 1-centimeter cubes. what is the volume of the box?
Answer: 60 cm three squared
You can observe in the picture attached that the box is a rectangular prism.
The volume of a rectangular prism can be found with this formula:
Where "l" is the length, "w" is the width and "h" is the height.
You know that the lenght of each side of those cubes is 1 centimeter. Therefore, you can multiply the number of cubes on each side of the box by 1 centimeter in order to find the lenght, the width and the height of the box:
Now you can substitute the lenght, the width and the height of the box into the formula shown at the beginning of the explanation:
Finally, evaluating, you get that the volume of the box is:
223 units

X = ?
Answer:
x = 3
Step-by-step explanation:
The midsegment is half the sum of the parallel bases, that is
[tex]\frac{1}{2}[/tex] (3x + 3 + 4x + 2) = 13
[tex]\frac{1}{2}[/tex] (7x + 5) = 13 ( multiply both sides by 2 )
7x + 5 = 26 ( subtract 5 from both sides )
7x = 21 ( divide both sides by 7 )
x = 3
