The sum of three consecutive odd numbers is 159. What is the smallest of the three numbers ?

1 answer:

6 0

Since we don't know where to start, we can always give that a variable which in this case, it's X. Since we are finding the sum of three consecutive odd numbers, we will be skipping numbers so we can add 2 each time. Now, let's set up an equation.

<h2>X + X + 2 + X + 4 = 159</h2><h2 /><h2>3x + 6 = 159</h2><h2> -6 -6 ← subtract 6 on both sides</h2><h2 /><h2> 3x = 153</h2><h2> ÷3 ÷3 ← divide both sides by 3</h2><h2 /><h2> X = 51</h2><h2> X + 2 = 53</h2><h2> X + 4 = 55</h2><h2 />

Therefore, the smallest of our three consecutive integers is 51.

Write a polynomial function of minimum degree with real coefficients whose zeros include those listed. Write the polynomial in s

r-ruslan [8.4K]

The first thing you should do is to determine all the zeros, and you will have 7, -11, 2 + 6i, 2 - 6i.
After that you have to <span>subtract and (x) from every each zero that you have above, which means
</span> $7-x, 

 -11-x, 

2 + 6i-x,

 2 - 6i-x
$
<span>And the last step is to multiply them together, and that's all you need!
</span> $(7-x)(-11-x)(2 + 6i-x)(2 - 6i-x)$
<span>I am pretty sure that everything hase become clear! Regards.</span>

How many dots will figure n have? Explain how you know this.

LenKa [72]

N = ((n-1) + 4) + 4, to my understanding.
although your answers seem right written in the columns, but your method of applying numbers to equation seems incorrect in 'expand' column. for example, answer for 3 should be something like this...
3 21 17+4
4 25 21+4
hope it helps.
