Solve by factoring. Think about what numbers multiply to be -36 (the last term) BUT also subtract/add up to be -5, which is the middle term. The answer to this is 4 and -9. Therefore, the two factors are (x-9)(x+4)

In a horse race, the odds in favor of the first horse winning in an 8-horse race are 2 to 5. The odds against the second horse w

Nataly_w [17]

The probability that the first horse wins is 2/7. The probability that the second horse wins is 3/10. Since the events that the first horse wins and the second horse wins are shared exclusive, the probability that either the first horse or the second horse will win is :

2/7 + 3/10= 41/70

Hope this is correct.

Vesnalui [34]

38.4 is the area. it’s 8.5 ft long so you do 8.5x2 and you get 17, and then for 10.7 you do 10.7x2 and get 21.4, then you add 21.4 and 17 together.

Rearrange the equation so m is the independent variable.<br> -2m-5n=7m-3n<br> n=___

Aneli [31]

<h2>Answer:</h2>

The equation is given by:

$n=\dfrac{-9}{2}m$

<h2>Step-by-step explanation:</h2>

We are given a equation in terms of the variable m and variable n as follows:

$-2m-5n=7m-3n$

Now, we are asked to find the equation in terms of m i.e. we have to consider m as independent variable and n as dependent variable since it's value is to be expressed in terms of m.

Now, we add 5n on both the sides of the equation to get:

$-2m=7m-3n+5n\\\\i.e.\\\\-2m=7m+2n$

Now, we subtract 7m from both the sides of the equation to get:

$-2m-7n=2n\\\\i.e.\\\\2n=-9m\\\\n=\dfrac{-9}{2}m$
