Question: (5x-8)/(45x^2--42x-48) a.) 9x - 48 b.) 9x - 23 c.) 9x - 6 d.) 9x + 6

To solve this problem you must apply the proccedure shown below:

1. You have the folllowing expression given in the problem above:

2. The first thing you must do is to factor the denominator, as following:

3. Now, simplify it and apply the distributive property in the denominator:

The answer is:

c. 27 units.

step-by-step explanation:

we are told that in circle a, ∠bae ≅ ∠dae.

we can see from our given diagram that in and ;

, as these are radii of our given circle.

therefore, by sas congruence postulate.

hence, side be will be equal to side de as corresponding parts of congruent triangles are congruent. so we can set an equation to find the value of x as:

now let us substitute x=17 in the expression for the length of be.

therefore, length of be will be 27 units and option c is the correct choice.
