X^2+3(X+2)=24
X^2+3x+6-24=0
X^2+3x-18=0
(X+6)(X-3)
X+6=0. X-3=0
X=-6. X=3

. Only 3 and 5 must be a odd integer

What are the side lengths of the equilateral triangle?

Alchen [17]

$5x + (6x - 5) + (3x + 10) = 360$

$5x + 6x - 5 + 3x + 10 = 360$

$11x - 5 + 3x + 10 = 360$

$14x + 5 = 360$

$14x = 360 - 5$

$14x = 355$

$x = 25.36$

$x = 25.36$

$5x = 5 \times 25.36 = 126.8$

$6x - 5 = 6 \times 25.36 - 5 = 147.16$

$3x + 10 = 3 \times 25.36 + 10 = 86.08$

hawnda incorrectly found the distance between -26 and 25 by following these steps: Step 1: |25 – (-26)| Step 2: |25 – 26| Step 3

tekilochka [14]

Answer:

Step 2

Step-by-step explanation:

Step 2 is not correct. It should be abs(25 - - 26) = abs(25 + 26) = 51

Given that Step 2 is accepted (as - 1) then three is OK and and so is 4. But technically they are incorrect as well. I think you are likely to say that step 2 is the problem.

The roster form of The set of odd natural numbers greater than or equal to 5 and less than or equal to 11 .

Lunna [17]

Answer:

{5, 7, 9, 11}

Step-by-step explanation:

Roster form just means list the elements of the set in the brackets.

It says the elements are greater than or equal to five and less than or equal to 11. So we start at 5 and end at 11.

We list {5, 7, 9, 11} because these elements follow the rule that they must be odd natural numbers. Natural numbers are the numbers you can count starting from 0 like {0, 1, 2, 3, ...}.

Solve for x: 2sin^2(x) -sin(x)=1 over the interval 0 to 2pi

Zepler [3.9K]

$2\sin^2x-\sin x=1\ \ \ \ |subtract\ 1\ from\ both\ sides\\\\2\sin^2x-\sin x-1=0\ \ \ \ |subtitute\ \sin x=t\ where\ t\in[-1;\ 1]\\\\2t^2-t-1=0\\\\2t^2-2t+t-1=0\\\\2t(t-1)+1(t-1)=0\\\\(t-1)(2t+1)=0\iff t-1=0\ or\ 2t+1=0\\\\t=1\ or\ 2t=-1\to t=-\dfrac{1}{2}\\\\therefore\\\sin x=1\ or\ \sin x=-\dfrac{1}{2}\\\\Answer:\boxed{t\in\left\{\dfrac{\pi}{2};\ \dfrac{7\pi}{6};\ \dfrac{11\pi}{6}\right\}}$
