Pls hurry n solve A) The expression is not simplified because Julie multiplied incorrectly

B) Julie simplified the expression correctly

C) The expression is not simplified because Julie should have subtracted the radicands to get radical -6

D) The expression is not simplified correctly because Julie failed to simplify radical 8

What is the effect on the graph of the function f(x) = x2 when f(x) is changed to f(x) − 4?

Find the measure of anglec in the following triangle

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
