Steps result (2x-3)( 5x² - 2x +7) use the distributive property to multiply 2x times each term in the trinomial. 10x3 - 4x? + 14x use the distributive property to multiply -3 times each term in the trinomial. (result for this step only) 10x3 - 4x² + 14% - 15x2 - 6x - 21 (result for step 1 and 2) 10x3 - 19x2 + 14x - 6x-21 3 use the addition property to combine the x terms. use the addition property to combine the x terms. 4 10x² - 19x² +8x-21 in which step did fiona make an error?

Mario is working on his math homework and is asked to use the distributive property to rewrite the expression 6d - 3e + 9f. his answer is 3(d - e + 3f). which best describes mario's error, and what is the correct answer? a.)mario can use the distributive property, but he didn't properly factor the first term in the parentheses. his answer should be 3(25 - e + 3f). b.) mario cannot use the distributive property to rewrite this expression because 6, 3, and 9 do not have a common factor. c.)mario cannot use the distributive property, since one of the terms is subtracted. you only can use the distributive property for adding numbers. d.)mario's answer is correct.

Confused with these distributive property problems. i am asked to verify the distributive property in them but i dont get why one number is used twice for example; 6 × (2 + 10) 6 × 2 + 6 × 10 < --here in this part why is the 6 used twice after applying the distributive property? and why do you have to multiply by it afterwards?
