The area of a rectangular pool table is: x2 + 14x +40. What are the dimensions of the table? Formula: Area = (L) (W)

A(x + 8)(x + 5)
B(x + 20)(x - 2)
C(x + 4)(x + 10)
D(x +14)(x + 40)

the width is (x + 4) and the length is (x + 10)

Step-by-step explanation:

The area of a rectangle is given by A = L * W, where L is the length and W the width.  

If we factor the given x^2 + 14x + 40, we get (x + 10)(x + 4).  Thus, the width is (x + 4) and the length is (x + 10).

f(x) = - 2/3x + 5; f(5/2)

substitute 5/2 in for x:

f(5/2) = -2/3(5/2) + 5

simplify the right side:

f(5/2) = -5/3 + 5

f(5/2) = 10/3

answer:

f(5/2) = 10/3

i hope this you!
