Set up an equation.
width = x
length = 56 - 2x
Multiplying length * width makes area. 56x - 2x^2 = Area.
y = -2x^2 + 56x
Ax^2 + Bx = C
Solve for the vertex: x = -(b/2a)
-(56/-4) = 14
width = 14 ft.
length = 56 - 2(14) = 28ft.
14*28 = 392 sq. ft.
Answer:
x = 72/5
Step-by-step explanation:
One way you can solve this is by cross multiplying. Multiply 8 and 9 together and 5 and x. You will get 5x = 72. Then you divide 72 by 5 and you will get x = 72/5.
I hope this helps. Have a great rest of your day!
Answer: the answer is 31
Step-by-step explanation: if you do 149 X 2 then minis that by 360 it will give you 62 then you divide that by 2 to get 31
First, start with the basic line equation:
y = mx + b
Then, fill in what you know.
-4 = 2(3) + b
Solve for b
-4 = 6 + b
-6 -6
-10 = b
Now you have your equation:
y = 2x - 10
I hope this helps :)
I think its a because the question says one pipe fills it in 4 hrs, then 2 pipes in 6 hrs, so 3 pipes in 8 hrs?!!?
is this ok?
