If f(x) = 6x and g(x) = x + 6, find (f - g)(1).

(f-g)(x)= f(x)-g(x)

=6x-x-6

=5x-6

(f-g)(1)= 5(1)-6

=5-6

= -1

Step-by-step explanation:

to find the perimeter of the rectangle this is the expression:

x-9+x-9+3x-4+3x-4=138

if we simplify it:

8x-26=138

remember, 138 is what it all adds up to

the length is 11.5cm

the width is 57.5cm

the area is 661.25cm^2

the answers might not be correct use at own risk

9 sandwiches per hour
