Here is how to work the problems and write the expressions.
Answer:
Find the total pens to start with by multiplying the number of boxes by the number of pens in each box:
22 x 19 = 418.
Now subtract the number of pens left:
418 - 71 = 347
He gave out 347 pens.
125 and 8 are perfect cubes.
125 = 5^3
8 = 2^3
125 - 8 = 5^3 - 2^3
Answer:
Length of Line AC = 26 units
Step-by-step explanation:
Given:
Line AC = [3x + 1] + 8
Line BC = [x - 2] + 2
Find:
Length of Line AC
Computation:
Line AB ║ Line L
So,
Using Mid-Point theorem;
[3x + 1] / 8 = [x - 2] / 2
2[3x + 1] = 8[x - 2]
6x + 2 = 8x - 16
8x - 6x = 16 + 2
2x = 18
x = 9
So,
Line AC = [3x + 1] + 8
Line AC = [3(9) + 1] + 8
Line AC = [27 + 1] + 8
Line AC = 28 + 8
Length of Line AC = 26 units
