Answer 1

the answer is 49

Explanation:

got it on the test

Answer 2

D.65

Explanation:

a=2

b=6

c=5

Calculating the value of
`\[7b-4a+6+c^(2)\]`,

=
`\[7*6-4*2+6+ 5^(2)\]`

=
`\[42-8+6+ 5^(2)\]`

=
`\[42-8+6+ 25\]`

=
`\[34+6+ 25\]`

=
`\[40+ 25\]`

=
`\[65\]`

Hence the value of the given expression
`\[7b-4a+6+c^(2)\]` is equal to 65.

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