In the room where you're sitting right now, the angle on the floor
where the bottoms of two walls come together is 90 degrees.
Answer: 
Step-by-step explanation:
- The equation of the line in point-slope form is:

Where m is the slope and
is a point of the line.
- The equation of the line
is written is slope-intercept form, where the slope is
.
- By definition, when two lines are perpendicular to each other, the slopes are the negative reciprocals. Therefore, the slope of the perpendicular line must be -3.
- Substitute the point P and the slope -3 into the equation in point-slope form, therefore, you obtain:

Answer:
4
Step-by-step explanation:
25- 9.5 is 15.5 and 4 ×3.75 is 15 you would have still have .5 cents
Answer:
14
Step-by-step explanation:
When you sqaure a number you multiply it by itself once so it would be (3x3) + 5. Rmemeber PEMDAS, so you multiply 3x3 first to get 9 and then you add 5 to get 14.
