<span>I think you meant 6x²+13x-5 so first thing we have to do is factor it which is really quite tricky with this kind of trinomial so first take ac which is 6 times -5 so -30 now figure out factors of -30 that will add up to 13 how about 15 and -2 now that we have the factors write the equation again</span>

<span /><span> 6x²+15x-2x-5  </span>split the equation in half<span />

<span>6x²+15x   -2x-5 so out of the first equation we can pull a 3x out</span>

<span>3x(2x+5) and out of the second we can pull a negative 1</span>

<span>3x(2x+5) -1(2x+5) rewrite it</span>

<span>(3x-1)(2x+5) so the 3x-1 is the factor we already had so the other side is (2x+5)</span>

<span>

Suppose that the height (in centimeters) of a candle is a linear function of the amount of time (in hours) it has been burning.
Alborosie
Assume that the rule connecting height of the candle to time is a linear one.  If you do, then we have to find the equation of this line, and then use this equation to predict the height of the candle after 11 hours.

Two points on this line are (6,17.4) and (23, 7.2).  The slope is thus
         7.2-17.4           -6
m = ---------------  =  -----------  or   -3/5.
           23-6                 10

Find the equation of the line.  I'm going to use the slope-intercept formula:

y = mx + b  =>   7.2 = (-3/5)(23) + b.  Solving for b,   b = 21.

Now    we know that y = (-3/5)x + 21

Let x=11 to predict the height of the candle at that time.

y = (-3/5)(11) + 21 = 14.4 inches  (answer)

Answer:

Step-by-step explanation:

<h2>A rocket is launched from a tower. The height of the rocket, y in feet, is related to the time after launch, x in seconds, by the given equation. Using this equation, find the time that the rocket will hit the ground, to the nearest 100th of second. </h2><h2>y=-16x^2+129x+119 </h2><h2>y=−16x  </h2><h2>2 </h2>

n the right triangular prism below, BG FC The volume of the prism is 900 cubic centimeters. The height of the prism is 15 centim
Bad White [126]
12 cm

Remember, V=Bh

-I think I did the process incorrectly but this is what I did:
900=(10)(15)
900=150 (divide 150 on both sides)
you get 6 but then I multiplied by 2 and got 12.
The answer 12 is correct though so I hope this helped! and if someone could explain the process better that would be great lol.

Find the least common multiple of 14 and 6.<br> Answer:
Oksanka [162]

Answer:

42

Step-by-step explanation:

First I multiplied 14 by 6, obtaining 84.  Next, I divided that by 2, obtaining 42.  This 42 is evenly divisible by both 14 and 6.  Thus, the LCM is 42.
