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:
(9,5)
Step-by-step explanation:
10+8/2=18/2=9
6+4/2=10/2=5
Answer:
243.84
Step-by-step explanation:
We change feet to inches, and inches to cm.
1 ft = 12 in.
1 in. = 2.54 cm
8 ft * (12 in.)/(1 ft) * (2.54 cm)/(1 in.) = 243.84 cm
8 ft = 243.84 cm
