Answer:

f(3) = 23

Step-by-step explanation:

To evaluate f(3) substitute x = 3 into the expression

f(3) = 2(3)² + 5 $\sqrt{3-2}$

= (2 × 9) + (5 × $\sqrt{1}$ )

= 18 + (5 × 1) = 18 + 5 = 23

Answer:

55/43

Step-by-step explanation:

(x/y) = 7/3, (x^2/y^2)=49/9, multiply by 3 above and multiply 2 below, 3x^2/2y^2=147/18. Next apply C&D and you will get (3x^2+2y^2)/(3x^2-2y^2)=(147+18)/(147-18)=165/129=55/43
