ines are undefined. C.The slopes of the two lines are zero. D.The slopes of the two lines are negative reciprocals.
1 answer:
Answer:
Option D is correct that is The Slopes of two lines are negative reciprocals.
Step-by-step explanation:
Perpendicular lines are the lines which intersect each other at right angle or make 90° angle with each other.
we that the Slope of perpendicular lines are equal to -1
Therefore, Option D is correct that is The Slopes of two lines are negative reciprocals.

It's not that hard of a problem you just have to read in-between the lines
So you make them into an improper fraction with a common denominator. so it would be 18/4 - 7/4, and it equals 11/4, or 2 & 3/4!
Answer:

Step-by-step explanation:
For question #1:

For question #2:

See the attached figure
we know that
[<span>the area of the trapezoid]=[area rectangle]+2*[area triangle]
</span>[the area of the trapezoid]=[14*12]+2*[12*2/2]=192 in²
the answer is 192 in²
