$2x^{2}$ - 3x - 35

Step-by-step explanation:

(2x + 7)(x - 5) = $2x^{2}$ - 10x + 7x - 35 = $2x^{2}$ - 3x - 35

Mathematics

m can only be equal to 1

Step-by-step explanation:

Range of f(x) = Range of g(x)

$\sqrt{mx} =m\sqrt{x}$

Squaring both sides,

$(\sqrt{mx}) ^{2} =(m\sqrt{x} )^{2}$

$mx=m^{2} x$

$m=m^{2}$

$m^{2} -m=0$

m(m-1) = 0

m cannot be 0.

So, m - 1 = 0 and m = 1.

So, m can boly be 1.
