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.

answer: -2+√x,-2-√x

i hope this , i don't know if you're looking for a pair or not.

5/20 so 25%

step-by-step explanation:

1. 180°. the sum of the interior angles of a triangle is 180°, for the equilateral triangle that it has three equals side is 60°+60°+60°=180°.

2. 60°. each interior angle of a equilateral triangle is 60°

3. 120°. the measure of ∠m is 120°, the sum of the angles ∠m and ∠n is equal to 180°. so, in order to find the measure of ∠m, we have ∠m+∠n=180° > ∠m=180°-∠n > ∠m=180°-60°=120°.

4. 360°. the sum of the exterior angles of an equilateral triangle is ∠m+∠r+∠x=120°+120°+120°=360°. the exterior angles of any triangle always add 360°.

did u ever get the answers? i need
