Answer:

92400m

Step-by-step explanation:

Find the volume of the two rectangles.

Volume of a rectangle: length*width*height

The first, larger rectangle: 64*60*28=107520m

The second, smaller rectangle: 18*30*28=15120m

Subtract the two rectangles' volumes for the building's total volume.

107520-15120=92400m

Help me please with this Simplify. 5a-12a

Oduvanchick [21]

It helps to imagine the variable a sort of as a unit. Like with 5 minus 12 lemons, it has no bearings on the addition/subtraction here.

Factor out a and subtract.

$5a-12a \\ (5-12)a \\ \boxed{-7a}$

Line j passes through points 1,6 and 7,1 line k is parallel to line j. What is the slope of line k?

Mashutka [201]

Slope formula m = (y2-y1) / (x2 - x1)
m = (1 - 6) / 7 - 1)
m = -5 / 6

Slope or parallel lines are the same
Slope = -5/6
