Answer:
the last one
Step-by-step explanation:
substitute the x values
Both students are correct because polynomials can be grouped in different ways to factor. Both ways result in a common binomial factor between the groups. Using the distributive property , this common binomial term can be factored out. Each grouping results in the same two binomial factors.
Answer:
7m^4-52m^3-28m^2+67m+42
Step-by-step explanation:
(7m^2-3m-7)(m^2-7m-6)
7m^4-3m^3-7m^2-49m^3+21m^2+49m-42m^2+18m+42
7m^4-3m^3-49m^3-7m^2+21m^2-42m^2+49m+18m+42
7m^4-52m^3-28m^2+67m+42
Answer:
$30
Step-by-step explanation:
Let the price of sweatshirt be $x.
Discount percentage = 30%
Discount in dollars = 30% of $x
Discount in dollars = 30/100 of $x = $ 30x/100
Given that discount in $ is 9
thus
30x/100 = 9
x = 9*100/30 = 30
Thus, the original price is $30
