Is it possible for 2 lines with negative slopes to be perpendicular? Why or why not?

No

Step-by-step explanation:

Perpendicular lines have negative reciprocal slopes, for example:

2/3 and -3/2

It is not possible for 2 lines to have negative slopes and be perpendicuar. This is because a slope must be negated to get the perpendicular slope.

rectangle: 9 1/8 x 4 1/9 = 37 37/72in

parallelogram: b times h= 10.3 x 6.2 = 63.86

trapezoid: a+b/2 times h= 42.5

volume of prism: l times w times h= 36

step-by-step explanation:

first you will have to convert 3/4 into a decimal

which is .75

then you will have to divide 1.5 by .75

which is 2

no you have to divide
