The exclamation mark means "factorial". We start with the given number and count down til we reach 1. We multiply all of the values in the countdown

6! = 6*5*4*3*2*1 = 30*12*2 = 360*2 = 720
3! = 3*2*1 = 6

So because
6! = 720
3! = 6

This means,
(6!)/(3!) = 720/6 = 120

Answer: 120

Find the distance of the point (3,4) from the midpoint of the line joining (8,10) and (4,6)

Elis [28]

Answer:

Distance between point $(3,4)$ and midpoint of line joining $(8,10)$ and $(4,6)$ = $5$ units.

Step-by-step explanation:

Given:

Points:

$A(3,4)\\B(8,10)\\C(4,6)$

To find distance from point A to midpoint of BC.

Midpoint M of BC:

$M=(\frac{x_1+x_2}{2},\frac{y_1+y_2}{2})\\$

$M=(\frac{8+4}{2},\frac{10+6}{2})\\$ [Plugging in points $B(8,10)\ and\ C(4,6)$ ]

$M=(\frac{12}{2},\frac{16}{2})\\$

$M=(6,8)\\$

Distance between A and M:

$D=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2} \\$

$D=\sqrt{(6-3)^2+(8-4)^2} \\$ [Plugging in points $A(3,4)\ and\ M(6,8)$ ]

$D=\sqrt{(3)^2+(4)^2} \\$

$D=\sqrt{9+16} \\$

$D=\sqrt{25} \\$

$D=\pm5$

Since distance is always positive ∴ $D= 5$ units

Write this fraction as a sum or difference.<br><br> 17. 9p-63

Alex787 [66]

P=7 because when you do bring 63 on the other side it'll be 9p=63 and after that divide both sides by 9 and you'll have p=7

I need the answer asap!!

slamgirl [31]

Answer:

Step-by-step explanation:

x² × 2x² = 2x^4 (2x to the power of 4)

x² × -3x = -3x³

+3 × 2x² = 6x²

+3 × -3x = -9x

2x^4 , -3x³ , 6x², -9x

In bold are the bottom two
