What are the factors of 25x4 − 49y2?

What expression is equivalent to 42x-56y

Write 5(6x+4)-2(5x-2) in the form a(bx+c) where a,b and c integers and a> 1

Match the following reasons with the statements given to create the proof. 1. do = ob, ao = oc sas 2. doc = aob given 3. triangle cod congruent to triangle aob vertical angles are equal. 4. 1 = 2, ab = dc if two sides = and ||, then a parallelogram. 5. ab||dc if alternate interior angles =, then lines parallel. 6. abcd is a parallelogram cpcte
