When you have a right triangle, you can use the Pythagorean Theorem to find the missing side length. (this can only be used for RIGHT triangles)
Pythagorean Theorem:
a² + b² = c² [c is the hypotenuse, or the longest line]
Since you know b = 8 and c = √73, plug it into the equation
a² + 8² = (√73)²
a² + 64 = 73
a² = 9
a = √9
a = 3
Answer:
6
Step-by-step explanation:
Each centimeter is equal to .01 meters
Or 100 centimeters = 1 meter
So if we convert Paula’s painting perimeter of 1.47 meters to centimeters, it would be 147 centimeters.
Now, since each ribbon comes in pieces that are each 25cm, we know are left with an easy division problem 147 divided by 25 or 5.88.
Since she needs the least amount of ribbons that it would take to wrap around the perimeter of the painting, we know it would be 6 because 6x25 = 150cm.

Step-by-step explanation:
I find it hard to believe that you were asked to find the solution to a cubic by any other method than graphing it, which I have given below. Not only that, the numbers are very awkward.
The best you could do I think is equate the two equations after you have looked at the graph.
The x value must satisfy
0.5(x - 4) = 2x^3 - 2x - 3
0.5x - 2 = 2x^3 - 2x - 3
2x^3 + 0.5x - 2x - 3 +2 = 0
3x^3 - 1.5x - 1 = 0
from which you can get y
My calculator gives the solution as
x = 0.5
y = - 1.75
I have corrected the mistake I made doing this. The answer is now correct. The graph shows the original two equations which agrees with the combined equation given above.
3gal/min divide 36gallons into 12 minuetes and then the quotient is 3 and take the units to result in 3gal/min
