Let b= length and a=width
Area= a*b and the problem said b=2a+3 (the length is 3ft more than double the width)
Replace b into Area formula:
Area= a*(2a+3) and we know that Area=77ft from the problem, so:
77=2a^2+3a now order and equal to zero:
2a^2+3a=77 now solve this with quadratic formula and you will get so values for a: -7ft and 5.5ft as you know the dimensions could not be negative so the correct answer for "a" side is 5.5ft, for getting the b side you haeve to replace a=5.5 into b=2a+3 and you will get b=2*5.5+3= 14ft.
Finished.
Answer
36/9= 4
Step-by-step explanation:
This is a fraction equal to
36 gallons ÷ 9 minutes
We want a unit rate where
1 is in the denominator,
so we divide top and bottom by 9
36 gallons ÷ 9
9 minutes ÷ 9
=
4 gallons
1 minute
=
4 gallons
minute
= 4 gallons per minute
5 Hope I helped. Have a good day
The x coordinate is halfway between 2 and 10 = 2 + (10-2)/2 = 2+4 = 6
so midpoint is C (6,3)
X= 48x^2
