what is the value of $\frac{6}{x}+2x^{2}$, when $x = 3$?\n8\n11\n14\n20
Answer
Explanation:
Step1: Substitute x = 3 into the first term
Substitute (x = 3) into (\frac{6}{x}), we get (\frac{6}{3}=2).
Step2: Substitute x = 3 into the second term
Substitute (x = 3) into (2x^{2}), we have (2\times3^{2}=2\times9 = 18).
Step3: Add the two results
Add the results of the two - steps: (2 + 18=20).
Answer:
