Let x represent the number:
2/3(x)+15=9
2/3(x)= -6
x= -6/(2/3)
x= -6*(3/2)
x= -9
Answer:
Value of X: X=2
Length of One Side: 31
Area: 961u^2
Perimeter: perimeter = 124
Step-by-step explanation:
Set the sides equal to each other, simplify and then use quadratic equation. One result is positive and the other is negative, shape's sides have to be positive so use the positive value for X.
answer will be 2÷18=9
and the answer is 9
