Answer:
Frankie have 6 coins
Step-by-step explanation:
For every 5 coins Carmen gets ,she gives 2 to her brother Frankie
Out of 5 coins, Carmen given 2 to her brother Frankie
So Carmen has 3 coins and Frankie has 2 coins
Ratio of coins , Frankie to Carmen is
2: 3
We need to find the number of coins Frankie has if Carmen has 9 coins
ratio of Frankie to Carmen is x : 9
Now make a proportion and solve for x
Cross multiply it
2*9 = 3*x
18 = 3x
Now divide both sides by 3
so x= 6
Frankie have 6 coins

A. x²-14x+49; is a polynomial
Step-by-step explanation:
(x-7)² can be written as (x-7)(x-7)
Expanding the expression
x(x-7)-7(x-7)
x²-7x-7x+49
x²-14x+49 ⇒⇒A quadratic function, which is a polynomial of degree 2
This function demonstrates the closer property of multiplication in that the change in order of multiplication does not change the product. This is called commutative property.
(x-7)(x-7)
-7(x-7)+x(x-7)
-7x+49+x²-7x
x²-14x+49
