3.14*r^2=50.24 => r^2=16. => r=4. => circumference=2*3.14*4=25.12
Answer:
(3/2)
Step-by-step explanation:
A perpendicular line has a slope that has the negative inverse of the reference line. The green line's slope of <u>-(2/3) becomes (3/2) for a perpendicular line</u>. The red line has two points we can use to calculate slope, just to check.
(-3,-5) and (5,7)
Rise = (7 - (-5)) = 12
Run = (5-(-3)) = 8
Slope = (12/8) or (3/2)
Answer: x*(x-5)
Step-by-step explanation:
Plexiglass is a cuboid
which means that the area would be l*w
in the question it states that the width is 5 cm shorter than the length
since we dont know the values
we represent them as x
so using l*w
we write x*(x-5)
Answer:
Surface area is 72
The surface area unit is square centimeters, or 
Hope this helps!
5x + 15 you need to distribute the 5
