8n. 8 represents the number of hours she sleeps, and n represents the number of night she sleeps.
Answer:
16x^2-24xy+9y^2.
Step-by-step explanation:
Since this is in the form of (x-y)^2, we can plug it into x^2-2xy+y^2.
So, we get 16x^2-24xy+9y^2.
Since 1 foot = 12 inches,
5 feet x 12 inches = 60 inches
Jason would be 60 inches + 11 inches tall which would = 71 inches.
71 inches is greater than 63 inches.
And 71 in -63 in= 8 in.
Therefore, Jason is taller by 8 inches
Answer:
8. yes
9. no
10. yes
Step-by-step explanation:
8. A horizontal line (y=3) is perpendicular to a vertical line (x=0).
__
9. A horizontal line (y=2) is parallel to a horizontal line (y=-1/2). The lines are not perpendicular.
__
10. A parallelogram is a rectangle if the sides are perpendicular. The slopes of the short sides are rise/run = -1, and the slopes of the long sides are rise/run = +1. These values have a product of -1, so the sides are perpendicular. The figure is a rectangle.
Answer:
the x would equal 25 as 5x2 is 10 + 16x25 - 84 is 0.
