Let width of the rectangular plot be x meters
then total of widths = 2x
and the length would be (550 - 2x) meters.
so the area = x(550 - 2x) = 550x - 2x^2
to find the maximum are find the derivative and equate to zero:-
f'(x) = 550 - 4x = 0
x = 550/4 = 137.5 meters = width
length = 550 - 2(137.5) = 275
Maximum area is when width = 137.5m and length = 275m
X ≤ <span>− 3; First solve for the (), so </span><span><span>−<span>9x</span></span>−6</span>≥<span><span>−<span>3x</span></span>+12. Then you combine </span>Add 3x to both sides: <span><span><span>−<span>9x</span></span>−6</span>+<span>3x</span></span>≥<span><span><span>−<span>3x</span></span>+12</span>+<span>3x</span></span><span><span><span>−<span>6x</span></span>−6</span>≥<span>12
Same for 6 : </span></span><span><span><span>−<span>6x</span></span>−6</span>+6</span>≥<span>12+6</span><span><span>−<span>6x</span></span>≥18
</span><span>Divide both sides by -6; Your done!</span>
