Let x = length of the park
Let y = width of the park
Because the area is 392392 ft², therefore
xy = 392392 (1)
Because three sides of fencing measure 5656 ft, therefore
2x + y = 5656 (2)
That is
y = 5656 - 2x (3)
Substitute (3) into (1).
x(5656 - 2x) = 392392
5656x - 2x² = 392392
2x² -5656x + 392392 = 0
x² - 2828x + 196196 = 0
Solve with the quadratic formula.
x = (1/2)*[2828 +/- √(2828² - 4*196196)]
= 2756.83 or 71.17
Answer:
The possible dimensions are 2756.8 ft and 71.2 ft (nearest tenth)
Answer:
Step-by-step explanation:
To rationalize the denominator, you need to multiply the numerator and denominator by the radical in the denominator (aka. a factor of 1):
To fine when Camryn will practice both the trumpet in the flute again, you will list the multiples of 11 and 3 in order to find the least common multiple.
3, 6, 9, 12, 15, 18, 21, 24, 27, 30, 33
11, 22, 33
They both will happen on the 33rd day, so Camryn will have both lessons again in 33 days.
a) -3g +35
b)-12m+6
