Answer 2

have you learned algebra yet? like x y z a b c

Answer 3

Somewhat

Answer 4

That's why I want to practice over the summer

Answer 5

take x=sqrt(10).
then the expression becomes
\(\Huge 2.4*(\sqrt{10})+1*(\sqrt(10)\)
or
\(\Huge 2.4*x+1*x\)
or
\(\Huge 2.4x+x\)
or
\(\Huge 3.4x\)
but \(\Huge x=\sqrt{10}\)
so the answer must be
\(\Huge 3.4\sqrt{10}\)
I can give a few other explanations
