Answer:
s+s+s+s or s times 4
Step-by-step explanation:
The perimeter of a square is equal to 2l + 2w. In this case, 1l and 1w is equal to s. so 2(s) + 2(w) = 4s
The equivalent ratio is 1/4
Answer:
(2, - 9 )
Step-by-step explanation:
Since 2 is the output when - 9 is input to f(x)
Then reversing the procedure, that is the inverse gives an output of - 9 for an input of 2.
(- 9, 2) is a point on the graph of f(x), then
(2, - 9) is a point on the graph o the inverse function 
(x)
If r is the radius of a sphere its surface area = 4(pi)r^2.
If the radius is doubled then its surface area = 4(pi)(2r)^2 = 4*4(pi)r^2.
So the surface area becomes 4-fold or the increase in surface area is 300%.
Answer:
18 ft
Step-by-step explanation:
The area of a rectangle is given by
A = l*w
144 = 8w
Divide each side by 8
144/8 =w
18 =w
