Answer:
d
Step-by-step explanation:
5y-x=-20
5y=x-20
y=1/5x-20
1 foot= 12 inches
75 feet = x inches
12× 75= 900 inches
Step-by-step explanation:
the area is
A = length × width.
length = 3 × width
=>
A = 3 × width × width = 3 × width²
300 = 3 × width²
100 = width²
width = 10 ft
Using
(n-2)180 = 1440
n-2 = 1440÷180 = 8
n= 8+2 = 10
n = 10sides which is a decagon
Step-by-step explanation:
11+38=49 or 49-11= which also equals 38
