Answer:

D.65

Step-by-step explanation:

a=2

b=6

c=5

Calculating the value of [tex]\[7b-4a+6+c^{2}\][/tex],

= [tex]\[7*6-4*2+6+ 5^{2}\][/tex]

= [tex]\[42-8+6+ 5^{2}\][/tex]

= [tex]\[42-8+6+ 25\][/tex]

= [tex]\[34+6+ 25\][/tex]

= [tex]\[40+ 25\][/tex]

= [tex]\[65\][/tex]

Hence the value of the given expression [tex]\[7b-4a+6+c^{2}\][/tex] is equal to 65.

Among the given options, option D is the correct option.
