Answer 2

HOPE IT HELPS!!!!!!!!!!!!!!!!!!!!!!!!!!

Answer:

426

Step-by-step explanation:

9x^2+3x+2+4              (x=5)

=> 81x+3x+2+4

=> 84x+6  

=>when we put the value x=5

it will be:

(84*5)+6

=>420+6

=>426

or other way is (as you have not put the exponention mark ^)

it will be:

9 *(x^2)+3x+2+4

now when we put the value i.e.x=5

it will be:

=>9*(5^2)+(3*5)+2+4

=>(9*25)+15+2+4

=>225+15+2+4

=>340+6

=>346
