Answer:
Area of the shaded region= 82.2 cm²
Step-by-step explanation:
Please see attached picture for full solution.
Perimeter: P = 2L + 2W. In this problem L = W + 4 or W = L - 4. We want L, so let's eliminate W:
P = 2L + 2(L - 4) = 20 (all measurements in feet)
Simplifying,
2L + 2L - 8 = 20, or 4L = 28 ft. Thus, L = 7 ft.
The rectangle is 7 ft long.
Answer:

Step-by-step explanation:
we know that
In the function f(x) the inflection point is at 
In the function g(x) the inflection point is at 
so
the rule of the translation of f(x) to g(x) is equal to

That means-----> the translation is
units to the right and
units down
The equation of g(x) is equal to

therefore

N= 75 (let me know if you need more help)
