10. simplify the rational expression by rationalizing the denominator. 3 sqrt 160/sqrt 1350x a) 2 sqrt 15x/15x b) 3 sqrt 160/1350x c) 4 sqrt 15x/15x d) 4/ sqrt 45x 11.

Can someone check if i did this right since i really want to make sure it’s correct. if you do you so much

Is there an x intercept in the equation 60*1.15^x

For [tex]f(x) = 4x + 1[/tex] and (x) = [tex]g(x)= x^{2} -5,[/tex] find [tex](\frac{g}{f}) (x)[/tex]a. [tex]\frac{x^{2} - 5 }{4x +1 },x[/tex] ≠ [tex]-\frac{1}{4}[/tex]b. x[tex]\frac{4 x +1 }{x^{2} - 5}, x[/tex] ≠ ± [tex]\sqrt[]{5}[/tex]c. [tex]\frac{4x +1}{x^{2} -5}[/tex]d.[tex]\frac{x^{2} -5 }{4x + 1}[/tex]
