Giraud, in asserting the truth of the fundamental theorem of algebra had a method for verifying the roots of a polynomial equation. he called it his "first faction -the sum of all the roots", "second faction - the sum of the product of the roots taken two ata time" and the "third faction -the sum of the product of the roots taken three at a time" he also required that the terms of the polynomial equation be written alternately in both sides of the equality sign. given the polynomial equation -11x+38x-40 a) rewrite the equation so that the degrees alternate on each side of the equation. b) verify that the roots are 2, 4 and 5 after you find the first faction, second faction and third faction of the roots.

d. $180

step-by-step explanation:

if the dimensions of the room is 9ft by 12 ft, we have the area of the floor as,

so the area of the floor is 108 square feet, converting that into square yards we get,

the cost of carpet is $15 per square yard, therefore the cost of carpet for 12 square yards is,

hence, the cost of carpet is $180.

assuming the dimensions of the room be,

15 ft by 12 ft

so, the area of the floor of that room is,

we can convert 180 square feet into square yards, we know that,

1 sq ft = 0.111 sq yard

so, 180 square feet is,

so the area of floor is 20 square yards.

now, the cost of carpet is 15 dollars per square yard, therefore the cost of carpet for 20 square yards is,

so, it will cost $300.

answer: what are the answer choices?

step-by-step explanation:

i think you would have to divide the money he had saved, which is $2,000 by the time he plans on exercising which is 40 hours, and the answer you get should tell you the answer to your question.
