The expression that is equivalent to [(4a + 4)/2a] * [a²/(a + 1)] after simplification is; 2a
<h3>How to Simplify Fractions?</h3>
We want to simplify the expression;
[(4a + 4)/2a] * [a²/(a + 1)]
This expression can be further reduced to;
[(4a + 4)/2] * [a/(a + 1)]
Factorizing the numerator to get;
[(4(a + 1)/2] * [a/(a + 1)]
(a + 1) will cancel out to get;
2a

4x = 2/5 is the same equation
Multiply 1/4 on both sides to clear the 4.
x = (2/5)(1/4) =2/20= 1/10
CHECK
(1/10)* 4= 4/10 = 2/5
As from the question,
x = 60°
πd = 12π
Using the Arc Length formula,
x/360° × πd
= 60°/360° × 12π
= 2π
Ans: B
In order to find the discriminant:
b^2-4ac
A= 1, B= 6, C=8
(6)^2-4(1)(8) = 4
Therefore, the equation has one real solution
