Answer:
I'll help out a bit:
Step-by-step explanation:
So ANY number in a square root is irrational(Non-terminating and no pattern)
Pi is also irrational
But ANY number that can be expressed as a fraction is rational(Also Whole numbers, natural numbers, etc.)
Hope this helps!
The length is 9.
The formula to find the perimeter of a rectangle is
2L + 2W = P.
2L + 2(4) = 26.
2L + 8 = 26.
2L + 8 (-8) = 26 (-8).
2L = 18.
2L/2 = 18/2.
L = 9.
Answer:
Hm I dont know if im right but im thinking it's a scalene, because the sides are not equal, or a obtuse triangle, because one side is more than 90 degrees. Hope this helps!
Answer: -1/2, 0
Step-by-step explanation:
x=0 , y=2x-5 and y=mx+9 form a right angle. So, y=mx+9 is either perpendicular to x=0 or y=2x-5 because the angle between x=0 and y=2x-5 is not 90 degrees. The product of slopes of perpendicular lines equals to -1.
Thus, m=-1/2 if it is perpendicular to y=2x-5. And y=c, for some constant if it is perpendicular to x=0. So y=0x+9 fits the bill. (m=0, in this case)
