Using the rational root theorem, it is found that your friend is correct.
<h3>What is the rational root theorem?</h3>
It is a theorem that states that for a polynomial with integer coefficients, with q being the factors of the leading coefficient and p being the factors of the constant, every <u>possible rational root</u> is the format .
In this problem:
The leading coefficient is 1, hence it's only factor is , thus guaranteeing that every possible rational zero is an integer, which means that your friend is correct.
The length is 19.5 feet. this is because when you add the yards, it equals 15 feet. Next, add 1 + 2 feet from the first and second jump. 10+8 inches equal 1.5 feet. Next, add 15 feet+3 feet+1.5 feet to get 19.5 feet.
I'm guessing the question is meant to be "<span>If the radius of a circle with a area of 5.3 mm squared is multiplied by 5, what will the new area be?", so i'll answer that.
