The answer is 8. 8 squared is 64 plus 8 is 72
[6 x 2 - 5] x 2
= (12 - 5 ) x 2
= 7 x 2
=14
Given:
The equations are:
To find:
The equation that show the relationship between a and c.
Solution:
We have,
...(i)
...(ii)
Equation (i) can be rewritten as:
...(iii)
From (ii) and (iii), we get
Therefore, the required equation is .
So we start at -10. Because he descends 3 feet, We subtract 3, getting -13. He then rises 6 feet. -13 + 6 = -7. The diver is now at -7 feet.
