Midpoint Formula [3D]: $(\frac{x_1+x_2}{2},\frac{y_1+y_2}{2}, \frac{z_1+z_2}{2} )$
Distance Formula [3D]: $d = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2+(z_2-z_1)^2}$

Step-by-step explanation:

Step 1: Define

Point A(1, 2, -1)

Point B(-3, -6, 2)

Point C(3, -2, 0)

Step 2: Find Point D

Simply plug in your coordinates B and C into the midpoint formula to find midpoint

Substitute [MF]: $(\frac{-3+3}{2},\frac{-6-2}{2}, \frac{2+0}{2} )$
Add/Subtract: $(\frac{0}{2},\frac{-8}{2}, \frac{2}{2} )$
Divide: $(0,-4, 1 )$

Step 3: Find distance d

Simply plug in the 2 coordinates A and D into the distance formula to find distance d

Substitute [DF]: $d = \sqrt{(0-1)^2+(-4-2)^2+(1+1)^2}$
Subtract/Add: $d = \sqrt{(-1)^2+(-6)^2+(2)^2}$
Exponents: $d = \sqrt{1+36+4}$
Add: $d = \sqrt{41}$

Which expression is equivalent to 8 p − 3 n + 4 q − 9 m ? 0 0 5 p n − 5 q m 5 p n minus 5 q m 4 ( 2 p + q ) − 3 ( n + 3 m ) 4 ti

Assoli18 [71]

Answer:

$8p - 3n + 4q -9m = 4[2p + q]- 3[n +3m]$

Step-by-step explanation:

Given

$8p - 3n + 4q -9m$

Required

The equivalent expression

$8p - 3n + 4q -9m$

Rewrite:

$8p - 3n + 4q -9m = 8p + 4q- 3n -9m$

Group to 2

$8p - 3n + 4q -9m = [8p + 4q]- [3n +9m]$

Factorize each group

$8p - 3n + 4q -9m = 4[2p + q]- 3[n +3m]$

What is the simplified form of ? 12x6 12x18 72x6 72x18

andreev551 [17]

Answer:

12*x^18

Step-by-step explanation:

144=(2^4)*(3^2)

then

sqrt (144 x^36)=sqrt (144)*sqrt (x^36)

sqrt (144)=sqrt ((2^4)*(3^2))=2² * 3=12

sqrt (x^36) =x^(36/2)=x^18

therefore

sqrt (144 x^36)=sqrt (144)*sqrt (x^36)=12*x^18

the answer is 12*x^18
