Answer:
B
Step-by-step explanation:
7. You are finding the area of the box. Not the cube, just a surface. Length times width of the surface. Eliminate other numbers and multiply
24.5×19.5
then
26×24.5
8. You are doing the same thing almost. Word problems are scary, but look for the numbers.
4inch ×8inch × 12inch
Find the volume
Multiply the volume by 3, that'd one answer
Devide the ORIGINAL volume by 2. don't divide the volume you multiplied by 3.
Perpendicular means that it has a slope that is the reciprocal of the original, and parallel means that the slopes are the same.
0.75 miles per hour I think....
