This math is too hard

x-1 over (x - 3) (x + 9)

Step-by-step explanation: Skip to main content Most aspects of mathematics can only be learned by hard practice. This holds true whether you want to develop your problem solving abilities or your computational skills. In math almost everything you learn is useful, even if you can't see it right away step 3 find the reasons don't just memorize.

step-by-step explanation:

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.
