Simplify sqrt72 -3sqrt12 + sqrt 192

vovikov84 [41]

Answer:

$6\sqrt{2}+2{\sqrt3}$

Step-by-step explanation:

Given expression:

$\sqrt{72}-3\sqrt{12}+\sqrt{192}$

Rewrite 72 as (36 · 2), 12 as (4 · 3), and 192 as (64 · 3):

$\implies \sqrt{36 \cdot 2}-3\sqrt{4 \cdot 3}+\sqrt{64 \cdot 3}$

Apply the radical rule $\sqrt{a \cdot b}=\sqrt{a}\sqrt{b}$ :

$\implies \sqrt{36}\sqrt{2}-3\sqrt{4}\sqrt{3}+\sqrt{64}{\sqrt3}$

Rewrite 36 as 6², 4 as 2², and 64 as 8²:

$\implies \sqrt{6^2}\sqrt{2}-3\sqrt{2^2}\sqrt{3}+\sqrt{8^2}{\sqrt3}$

Apply the radical rule $\sqrt{a^2}=a$ :

$\implies 6\sqrt{2}-3\cdot 2\sqrt{3}+8{\sqrt3}$

Simplify:

$\implies 6\sqrt{2}-6\sqrt{3}+8{\sqrt3}$

$\implies 6\sqrt{2}+2{\sqrt3}$

First of all, x =-1 (y don’t change) so first 2 answer is out.
Now mirror to x-1 >>>
A(0,-1)
0 >> -1 is left one step so -1 left one step is -2
A(0,-1) >> A’(-2,-1)

A(-5,0)
-5 >> -1 is right 4 step so -1 right 4 step is 3
A’(3,0)
This is correct
Answer is D

How many times greater is the value of the 7 in 874,699 than the value of

geniusboy [140]

Answer:

C. 10 times greater

Step-by-step explanation:

every time you move left a number space, the value increases by a multiple of 10x (the opposite is true for moving right)

for example:

1.0

10.0

100.0

10 is 10x greater than 1

100 is 10x greater than 10 or 100x greater than 1

*notice how the number 1 is moving one space to the left
