Undefined is the answer because there is no value for x
Line DE is 4 squares and Line BC is 8 squares.
The length of line DE is 1/2 of line BC
The answer is B because r is negative and less than the critical value.
Let
x---------> first positive integer
x+1------> second positive integer
x+2-----> third positive integer
we know that
(x+1)*(x+2)=72-------> x² +2x+x+2=72 -------> x² +3x-70=0
using a graph tool-------> <span>I solve the quadratic equation
</span>see the attached figure
the roots are
x1=-10
x2=7
the answer is
first positive integer is x=7
second positive integer is x+1=8
third positive integer is x+2=9
