Hey there! I'm happy to help!

If something is 11 less, we are subtracting 11.

-11

We have 11 less than seven times a number x.

7x-11

The word is means equals.

7x-11=-4

Now we need to isolate the x. We add 11 to both sides.

7x=7

We divide both sides by 7.

x=1.

Have a wonderful day! :D

8 square root 2<br><br>6 square root 18<br><br>14 square root 2<br><br>8 square root 18
True [87]
Work: 5√2 + √18
First you must find the largest perfect square in √18:
The perfect square happens to be 9
√18 => 9√2
You must then simplify 9 since it is a perfect square:
9√2 => 3√2
Then you must add both terms together:
5√2 + 3√2 = 8√2
Answer: 8√2 or 8 square root 2

I hope this helps you!
