if you meant x^2+9x+20 then it is (x+4)(x+5) you know that because 4+5=9 and 4x5=20 using FOIL

Answer:
162 revs
Step-by-step explanation:
-The distance to be covered is 1100 ft.
-The circumference of the tire is equivalent to the distance covered by the tire in one revolution.
#We find the tire's circumference in feet(1inch=0.08333)
We then divide the distance to be traveled by the tire's circumference to determine the number of revolutions made:
Hence, the tire makes approximately 162 revs.

Answer:
x=2.125
y=0
C=19.125
Step-by-step explanation:
To solve this problem we can use a graphical method, we start first noticing the restrictions and
, which restricts the solution to be in the positive quadrant. Then we plot the first restriction
shown in purple, then we can plot the second one
shown in the second plot in green.
The intersection of all three restrictions is plotted in white on the third plot. The intersection points are also marked.
So restrictions intersect on (0,0), (0,1.7) and (2.215,0). Replacing these coordinates on the objective function we get C=0, C=11.9, and C=19.125 respectively. So The function is maximized at (2.215,0) with C=19.125.
