For each unit increase in x, add 12. The function y = 12x is increasing and is a case of direct proportion.
28 is 2*2*7, so 2 and 7 are the primer factors of 28
Width = x
Length = 3x
Perimeter = x + x + 3x + 3x = 8x
He walked 3 rounds
3 x 8x = 24x
Total distance walked = 5280 feet
24x = 5280
x = 220
Shortest side is 220 feet
Answer:
x= 3sqrt2 y=3
Step-by-step explanation:
The triangle is isosceles triangle, which means 2 sides are congruent. Therefore, y =3
using the pythagorean theorem,
3^2+3^2=x^2
9+9=x^2
18=x^2
x=18 sqrt
3sqrt2
Answer:
C
Step-by-step explanation:
Note that 1 = , hence
9 = 9 × = =
