Answer: 2*√18 + 3*√2 + √162 = 18*√2
Step-by-step explanation:
I guess that the equation is:
2*√18 + 3*√2 + √162
And we want to simplify it.
first 18 = 9*2
then we can write:
2*√18 = 2*√(9*2) = 2*3*√2 = 6*√2
and 162/9 = 18
then we can write:
√162 = √(9*18) = √9*√18 = 3√18
now we can use the previous step: √18 = 3*√2
and:
√162 = 3*(3*√2) = 9*√2
now we can write our equation as:
6√2 + 3√2 + 9√2 = (6 + 3 + 9)√2 = 18*√2
And now we can not simplify it further more, so here we end.
The square root of 137,

can't be simplified anymore, not even by the method of taking out a perfect root

Thus, the answer is 11.70 (rounded)
Answer:
7 - 2x
Step-by-step explanation:
We start with
-2x + 7
And we can separate the terms
(-2x) (+7)
and move them around
(+7) (-2x)
7 - 2x is an equivalent expression.
You would have 18.08 kilometers. In order to solve you have to divide two hundred and seventeen along with twelve.
