well, you would use the equation P=2L+2W, or perimeter equals 2 time the length + 2 times the width. which would be 2*2+4*4= 20. you would need 20 feet of border. hope this helped ^-^
Answer:
r = 3.2
Step-by-step explanation:
If A varies inversely with the square of r, then A = kr^2
75 = k*4^2 = 16k
k = 75/16
Now A = (75/16)*r^2
48 = (75/16)*r^2
r^2 = 48(16/75) = 256/25
r =
= 16/5 = 3.2

Answer:
x = 8
Step-by-step explanation:
40 + 6x + 2 = 90 {Complementary angles}
Combine like terms
40+ 2 + 6x = 90
42 +6x = 90 {Subtract 42 form both sides}
6x = 90 - 42
6x = 48 {divide both sides by 6}
6x/6 = 48/6
x = 8
Step-by-step explanation:
i believe the answer is y=24
