Well you would have them work together which can possibly cut the work time in half. So if you have them both working then it can speed up the process to B. I hope this helped :D
Answer:
216 inches^3
Step-by-step explanation:
Volume= Length x Width x Height
Volume of Katie's cube is 3x3x3 (27 inches^3)
Malea's cube is 8x the volume of Katie's cube, so Malea's cube is 8 x 27, which is 216 inches^3
When 2 lines are parallel to each other mean than they have same gradient
y=5x +2
Gradient=5
Let the parallel equation be y=5x +c
Since this equation pass through (4,7), means that the point satisfy the parallel equation
7=5(4)+c
C=7-20=-13
So the parallel equation required is y=5x-13
Hope this can help.
