A student claims that -9i is the only imaginary root of a quadratic polynomial equation that has real coefficients.
a. What is the mistake in the student's claim? (2 points)
HINT: If there is another solution, what is it. If there is another solution, what
theorem is used to support your claim.
b. Write one possible factored polynomial that has the correct roots from part a by
filling in the missing parts to the polynomial below. (1 points)
C. Write the factored polynomial from part b in standard form. (1 points)

i you goofed up when writing this, because hnot is not a word minusf is not either. i cannot answer   because of that.

step-by-step explanation:

we'll this would mean that the dunk tank and the bounce house are the same for 20 hours because the 2 represents that the two activities, and the 20 represents the amount of hours they both are. so with this said, it means that the answer is c. the costs for a dunk tank and bounce house are the same for 20 hours.

c.the costs for a dunk tank and bounce house are the same for 20 hours.

hope this .

step-by-step explanation:

2.24/7

we have three similar triangles, because each has a right angle and shares an angle.   let's write the angles in order: opposite to short leg, long leg, hypotenuse.

cab similar to bad similar to cbd

or as ratios,

ca: ab: cb = ba: ad: bd = cb: bd: cd

we also know

ac = ad + cd

(ad+cd): ab: cb = ba: ad: bd = cb: bd: cd

(ad+cd)/cb=cb/cd

we have cb=6, ad=5 and seek x=cd.

we reject the negative root and conclude x=4

answer: 4
