X=-b/2a=4/14=2/7
Plug this value back into the function to find the corresponding Y value
Given that x is the number of chains;
7(4+3) = 7 * 7 = 49 feet
7 x 4 = 28
To get 33 is you add 28 and 5 to get 33
The answer is 4 (136y-21)
Explanation:
Factor 4 out of 544y.
4 (136y) - 12*7
Factor 4 out of -12*7.
4 (136y) + 4 (-3*7)
Factor 4 out of 4.
(136y) + 4 (-3*7)
4 (136y- 3*7)
Multiply -3 by 7.
4 (136y - 21)
