Answer 2

We have:

8a + 3b - 10 + $c^2$

To find, the value of 8a + 3b - 10 + $c^2$ is equal to:

Solution:

∴ 8a + 3b - 10 + $c^2$

Put a = 2, b = 5 and c = 4, we get

= 8(2) + 3(5) - 10 + $4^2$

= 16 + 15 - 10 + 16

= (16 + 15 + 16) - 10

= 47 - 10

= 37

∴ 8a + 3b - 10 + $c^2$ = 37

Thus, the value of  8a + 3b - 10 + $c^2$ = 37.
