2 triangle+square=23
square=60/triangle
2 triangle+60/triangle=23
2 triangle^2+60=23 triangle
2 triangle^2-23 triangle+60=0
solving quadratic equation we get
triangle=15/2 , 4
15/2 is not possible so triangle=4
square=15
Answer:
11
Step-by-step explanation:
You replace all the x with 12 when its f(12). if its f(3) you would replace all the x with 3.
So,
f(12)=2/3(12)+3
f(12)=8+3
f(12)=11
