We wish to write x + 3 (x − 3)(x + 1) as a sum a x − 3 + b x + 1 . let’s find a and b. set the two expressions equal and clear denominators (that is, multiply through by (x − 3)(x + 1) and cancel (x − 3)’s and (x + 1)’s as much as possible). plug in x = 3 and solve for a. use the same idea to find b. check your work by adding the two fractions together.

what graph

step-by-step explanation:

your answer is -9

step-by-step explanation:

80° is the measure of gh

step-by-step explanation:

circle f is congruent to circle j

we have two circle with center f and j.

both circles are congruent. the radius of the circle would be equal.

see the attachment for the circle.

we are given ∠efd ≅ ∠gjh

therefore, arc (ed) = arc (gh)     (∴ circle f is congruent to circle j)

but ∠dfe=80°=arc (ed)

therefore, arc (gh) = 80°

thus, 80° is the measure of gh
