Answer 2

Correct Question :-

8a + 3b - 10 + c² when

• a = 2
• b = 5
• c = 5

Answer :-

• The required number is 46.

Step-by-step explanation ::

Given that,

8a + 3b - 10 + c²

• a = 2
• b = 5
• c = 5

Solution ::

=> 8a + 3b - 10 + c²

=> 8*2 + 3b - 10 + c²

=> 16 + 3*5 - 10 + c²

=> 16 + 15 - 10 + c²

=> 16 + 15 - 10 + 5²

=> 16 + 15 - 10 + 25

=> 16 + 5 + 25

=> 16 + 30

=> 46

The required number is 46.

Now, Verification

• 8a + 3b - 10 + c² = 46

We have,

• L.H.S = 8a + 3b - 10 + c²
• R.H.S = 46,

By, putting the values of a, b and c,

=> 8a + 3b - 10 + c²

=> 8*2 + 3b - 10 + c²

=> 16 + 3*5 - 10 + c²

=> 16 + 15 - 10 + c²

=> 16 + 15 - 10 + 5²

=> 16 + 15 - 10 + 25

=> 31 - 10 + 25

=> 21 + 25

=> 46

Therefore,

• L.H.S = 46

And, we have R.H.S = 46, Therefore,

L.H.S = R.H.S

Hence, Verified!
