Answer:
b
Step-by-step explanation:
64 = 2x^2
32 = x^2
x = 4√2
ans is b
Move all terms to the left side and set equal to zero. Then set each factor equal to zero. Exact form:
X=0,1/5
Decimal form:
X=0,0.2
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:
Part A: x= 0.02 (rounded)
divide by 62
Part B: x= 0.02 (rounded)
divide by 60
