I think the correct answer from the choices listed above is the first option. The equation (m + 5)(m - 9) = 0 has <span>solutions of m = -5 and m = 9. Hope this answers the question. Have a nice day. Feel free to ask more questions. Thank you.</span>

Answer:

A. $(m+5)(m-9)=0$

Step-by-step explanation:

We have been given that an equation has solutions of $m=-5$ and $m=9$ . We are asked to the equation, which represents these solutions.

Let us check our given choices:

A. $(m+5)(m-9)=0$

Using zero product property, we will get:

$m+5=0\text{ (or) }m-9=0$

$m+5-5=0-5\text{ (or) }m-9+9=0+9$

$m=-5\text{ (or) }m=9$

Therefore, option A is the correct choice.

Find the difference. (9/x^2-9x)-(6/x^2-81)

Sunny_sXe [5.5K]

The difference is $\frac{3 x+81}{x(x-9)(x+9)}$

Explanation:

The expression is $\left(\frac{9}{x^{2}-9 x}\right)-\left(\frac{6}{x^{2}-81}\right)$

Removing the parenthesis, we have,

$\left\frac{9}{x^{2}-9 x}\right-\left\frac{6}{x^{2}-81}\right$

Factoring the terms $x^{2}-9 x$ and $x^{2}-81$ , we get,

$\frac{9}{x(x-9)}-\frac{6}{(x+9)(x-9)}$

Taking LCM, we get,

$\frac{9(x+9)-6x}{x(x-9)(x+9)}}$

Simplifying the numerator, we get,

$\frac{9x+81-6x}{x(x-9)(x+9)}}$

Subtracting the numerator, we have,

$\frac{3 x+81}{x(x-9)(x+9)}$

Hence, the difference is $\frac{3 x+81}{x(x-9)(x+9)}$

1 gallon minus 1 quart, 1 pint, and 1 ounce

just olya [345]

16 ounces = 1 pint
2 pints = 1 quart
4 quarts = 1 gallon

1 gallon - 1 quart = 3 quarts
3 quarts - 1 pint = 2 quarts and 1 pint
2 quarts and 1 pint - 1 ounce = 2 quarts and 15 ounces.

12 = x - 24<br><br> I think know the answer but I’m unsure of how to do it

weeeeeb [17]

Answer:

Step-by-step explanation:

you have to isolate your variable. To do this, you add 24 to each side. On the left side its 12+24 and on the right, its 24+(-24) which then equals zero. In simple terms, x=12+24

Step-by-step explanation:

No. of possible 7 digit codes

= 10^7

= 10000000

Probability = 1000/10000000

= 1/10000 or 0.0001
