Three roots of a fifth a degree polynomial function f(x) are -2, 2, and 4 + l. Which statement describes the number and nature of all roots for this function?
Of(x) has two real roots and one imaginary root.
O f(x) has three real roots.
O f(x) has five real roots.
O f(x) has three real roots and two imaginary roots.

yeah and

step-by-step explanation:

you know what it isnt great cheating

he used the algebra tiles correctly.

step-by-step explanation:

given : 3x(2x-1)

solution :

since he used algebra tiles .

armando's solution is the same in the solution shown in figure

as he distributed 2x into x and x and wrote them vertically

and also write   -1 vertically

and 3x into x and x and x and wrote it horizontally

performing the multiplication in the algebra tiles we get

and solving the given expression :

3x(2x-1)

since solving the expression using tiles   and solving the expression algebraically we get the same answer

thus   we can choose the first statement as the answer to this problem which is "he used the algebra tiles correctly".

n=9

step-by-step explanation:

7 times a number = 7n

decreased by 13 = 7n-13

same as is =

5 times the number = 5n

increased by 5 = 5n+5

7n-13 = 5n+5

2n=18

n=9

i don't see any
