900! is really 900 * 899 * 898 * 897 * 896 * 895 ......... * 3 * 2 * 1.

899 is really 899 * 898 * 897 * 896 * 895 ......... * 3 * 2 * 1.

$\bf \cfrac{900!}{899!}\implies \cfrac{900\cdot 899!}{899!}\implies 900\cdot \cfrac{899!}{899!}\implies 900\cdot 1\implies 900$

PLEASE HELP!<br><br> Reduce to simplest form.<br> 5/8 - (- 7/2)

Daniel [21]

Answer:

$\huge\boxed{\sf 4\frac{1}{8} }$

Step-by-step explanation:

$\sf =\frac{5}{8} - (-\frac{7}{2} )\\\\Rule : ( - *- = +)\\\\\=\frac{5}{8} +\frac{7}{2} \\\\LCM = 8\\\\\=\frac{5+28}{8} \\\\\=\frac{33}{8} \\\\=4\frac{1}{8}$

$\sf =\frac{5}{8}+ \frac{7}{2} \\\\=\frac{5+28}{8}$

$\sf =\frac{33}{8} \\\\=4\frac{1}{8}$

Hope this helped!

How do you write a quadratic equation in standard form?

Lemur [1.5K]

Answer:

Powers of the variable descending left to right
right side of the equal sign is 0

Step-by-step explanation:

For some constants a, b, and c, the standard form* is ...

ax^2 + bx + c = 0

___

It is nice if the leading coefficient (a) is positive, but that is not required.

The main ideas are that ...

Powers of the variable are descending
All of the non-zero terms are on the left side of the equal sign
Like terms are combined

_____

* This is the <em>standard form</em> for a quadratic. For other kinds of equations, when the expression is equal to zero, this would be called "general form."
