Answer:
Step-by-step explanation:
Given:
Radius of circular mirror, r = 6x
Length of metal frame, l = 18x
Area of square, As = l^2
Area of square = 18x × 18x
= 324 x^2.
Area of circular mirror, Ac = pi × r^2
= π × (6x)^2
= 36π x^2.
The expression for the area of the frame is subtracting the mirror from the metal frame = As - Ac
= 324x^2 - 36πx^2
= 36x2 (9 - π).
Given 460 
a) convert it into 
=> It means
and 
1 ft = 0.3048 m

1 gal = 3.78541 l
m^2[/tex].
b. 
c.Given= 
To find inverse, divide it by 1.
Inverse- 
Yes, 13 is the remainder.
