2. Answer: 35
Step-by-step explanation:
4x3 grid so 4!= 24 and 3!= 6 4+3=7 so 7! = 5040 now 7!/4!*3!=35.

Area of rectangle= length * hight
Answer:

Step-by-step explanation:
In this problem we have a horizontal ellipse, because the major axis is the x-axis
The equation of a horizontal ellipse is equal to

where
(h,k) is the center of the ellipse
a and b are the respective vertices distances from center
we have
vertices at (7, 0) and (-7, 0)
co-vertices at (0, 1) and (0, -1)
so
The center is the origin (0.0) (The center is the midpoint of the vertices)
a=7
b=1
substitute


Answer:
f(2) = 2
Step-by-step explanation:
Substitute x=2 for x, but there is no x on the right side of the equation.
So since it is a straight line of f(x) =4, for any x, f(x)=2
