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:
Area=154.062 
Step-by-step explanation:
As Circumference of a circle is given by;

As the circumference is 44m so we can calculate the value of r by using the above formula.

Now to Calculate the Area of a Circle.
As the area of a circle is,

For this question you just need to find the least common multiple of 18 and 30. That can be found by first finding the prime factorization of each number. 18 = 2 * 3 * 3 and 30 = 2 * 3 * 5. Then you multiply the 2 * 3 * 3 * 5, you ignore the 3 from 30 because 18 has more 3s. The answer is 90.
Answer:
q = 4
Step-by-step explanation:
this is your equation
8 + q = 12
rearrange to find q
q = 12 - 8
q = 4
