Answer: B. 2 = 3x + 10x2
Step-by-step explanation:
This is the concept of quadratic equations; We required to find the type of equation that can be solved using the model that has been used to solve the equation such that the answer is:
[-3+-sqrt(3^2+4(10)(2))]/(2(10))
The formual that was applied here was a quadratic formula given by:
x=[-b+\-sqrt(b^2-4ac)]/2a
whereby from the our substituted values above,
a=10,b=3 and c=-2
such that the quadratic equation will be:
10x^2+3x-2
Answer:
0 ways...
Step-by-step explanation:
First find one pair.
x and x + 1
2x + 1 = 100
2x = 99
x = 49.5
49.5 and 50.5
Since the only way is with decimals, there are 0 ways.
The surface area is 72ft^2
hope this helped!
