Answer 1

Thank you for posting your math question here at brainly. I think the choices for the above problem is the below, it can be found elsewhere. 

a. x = −5
b. x = −3
c. x = 3
d. x = 5

The answer is d. I hope it helps. 

Answer 2

Answer-

The axis of symmetry is  $x=5$

Solution-

The parabolic equation given is,

$h(x) = 6x^2-60x+147$

Here,  

a = 6, b = -60, c = 147

The equation of the axis of symmetry is,

$x=-\dfrac{b}{2a}$

Putting the values,

$\Rightarrow x=-\dfrac{-60}{2\times 6}\\\\\Rightarrow x=\dfrac{60}{12}\\\\\Rightarrow x=5$

Therefore, the axis of symmetry is $x=5$
