Answer:
x^2 + y^2 = 49
Step-by-step explanation:
For center (h,k) and radius r, eqution of the respective circle is
(x-h)^2 + (y-k)^2 = r^2
A rectangle is a two-dimensional shape with two sets of equal, parallel sides. These dimensions are the length (L) and the width (W). The formula for the rectangle's area is the product of the two dimensions. The formula for perimeter is
P = 2L + 2W
Since
A = LW = 64
W = 64/L
Substituting to the formula for perimeter would be,
P = 2L + 2(64/L)
P = 2L + 128/L
It could be any time, but I would say 10. 10*10=100
hope it helps!
Answer:
52
Step-by-step explanation:
(I replaced 
with 
since we are to find 
.)
(By the order of operations, we take care of the exponents before whatever else we have here.)
(By the order of operations, we take care of the multiplication as we see if left to right.)
(By the order of operations, we perform addition/subtraction as we see it left to right.)
(This completes the simplification.)
We could have also put this in our calculator as:
4(4)^2 - 2(4) - 4
This would have returned 52.
