3.53

Step-by-step explanation:

A=LW

L=x-2

w=x+3

A=10

(x+3)(x-2)=10

x^2+3x-2x-6=10

x^2+x-16=0

use quad. formula

(aprox 3.53)

or

aprox.  -4.53

we cant have an neg. area so 3.53's our best bet

h is the x-coordinate of the vertex

step-by-step explanation:

we have

in this function

the point represent the vertex of the function

so

h is the x-coordinate of the vertex

k is the y-coordinate of the vertex

54/3 is 18 so 18 is your answer
