Your friend claims that when a polynomial function has a leading coeffcient of 1 and the coefficients are all integers , every p
sammy [17]

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 \frac{p}{q}.

In this problem:

  • The leading coefficient is 1, hence it's only factor is q = 1, thus guaranteeing that every possible rational zero is an integer, which means that your friend is correct.

1. r - 29 = -2r + 19
Sphinxa [80]

Answer: r=16

Step-by-step explanation:

r-29=-2r+19

r=−2r+19+29

r=−2r+48

r+2r=48

3r=48

r=48/3

r=16

Hope this helps, now you know the answer and how to do it. HAVE A BLESSED AND WONDERFUL DAY! As well as a great Valentines Day! :-)

Answer ASAP<br><br> Find the area for this shape
Ivenika [448]
The shape is a trapezoid and its area formula is:

A = \frac{a+b}{2}h

a is a base length, b is another base length and h is the height.

A = \frac{3.1+11.9}{2}(10.8)
A = 81

So the area of the shape is 81yd²

PLEASE HELP! NO LINKS! TEN POINTS!<br><br> please explain it if you can!
Nata [24]
I think the answer would be 112cm.

To find the area of the triangle you need to do basexheight divided by 2.
8x10 divided by 2 = 40

To find the area of the rectangle
12x6=72

40+72= 112cm

I’m not sure if it’s right but I hope this helps.
