Step-by-step explanation:
Answer C)
Explanation:
MN + NP = MP
MP = 39
Therefore, 4(x + 5) + 2x + 1= MP
So, 4(x + 5) + 2x + 1= 39
(4x + 20) + 2x +1 = 39
So, (4x + 2x) + (20 + 1) = 39
6x + 21 = 39
Addition changes to Subtraction
So, 6x = 39 - 21
6x = 18
Multiplication changes to Division
x= 18/6
x=3
Therefore MN = 4(x + 5)
So, 4(3 + 5) = 4(8)
4(8) = 32
Therefore, MN = 32
Hope this helps!

It will cost about $0.72 for three pair of shoes assuming shoe box is rectangular shape having 12 square inches of packing paper.
Step-by-step explanation:
- Assuming a shoe box rectangle in shape and the same size is required.
- Length of rectangle box assuming to be 4 inches.
- Width of rectangle box assuming to be 3 inches.
- as we know area of rectangle is Length * Breath(Width) .
- 12 square inches is the total packing paper required for each box.
- To cover cost of three pairs of shoes $0.02 per square inch.
- Each box would cost about 12 square inches * 0.02 pr square inches.
- 0.24 square inches of packing paper will be required.
- let three pairs of shoes be x
- Total pairs of shoes would be= (12 * 0.02)*x
- Answer would be for 3 pairs of shoes = 0.24*3 = 0.72 square inches.
