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.
Assuming you are asking how many weeks, than the answer would be 17-32, because at 16 weeks the growth would be 4 cm, totaling at 11, but you need more than 11cm, and at 32 weeks it's at 15 cm.
Let's say the function for the discount is f and the function for the coupon is g f(x)= 0.1x g(x)= x-150 If you want to the the discount then the coupon, your composition function would look like this: f(g(x))=0.1(x-150) Hope this helps!
