Ihave know idea what to do and show work so i can understand you!
1.) k+3/4k-2 * (12k^2-3)
2.) x^2-16/6x * 7x/x+5
3.) q+5/2 * 4q/q+4
4.)y^2-9/-2y * -5y/y+3
-20x+15) divided by (2x-3)
-30+21) divided by (4x-6)
-4m-12m^6) divided by 2m^4

Given: ab ≅ cd and ad ≅ bc prove: abcd is a parallelogram. statements reasons 1. ab ≅ cd; ad ≅ bc 1. given 2. ac ≅ ac 2. reflexive property 3. △adc ≅ △cba 3. ? 4. ∠dac ≅ ∠bca; ∠acd ≅ ∠cab 4. cpctc 5. ∠dac and ∠bca are alt. int. ∠s; ∠acd and ∠cab are alt. int. ∠s 5. definition of alternate interior angles 6. ab ∥ cd; ad ∥ bc 6. converse of the alternate interior angles theorem 7. abcd is a parallelogram 7. definition of parallelogram what is the missing reason in step 3? triangle angle sum theorem sas congruency theorem sss congruency theorem cpctc
