Let "radical 2" be represented by "r."
Then you are to simplify 4r + 7r - 3r. This comes out to 11r - 3r = 8r.
The answer is 8 radical 2.
The formula of a lateral area of a cylinder:

We have r = 9 yd and H = 4 yd. Substitute:

Answer:
<h2>The answer is 35</h2>
Step-by-step explanation:
Since the triangle is a right angled triangle we can use Pythagoras theorem to find the missing side b
Using Pythagoras theorem we have
a² = b² + c²
where a is the hypotenuse
Substitute the values into the above formula and solve
That's
<h3>

We have the final answer as
<h3>35</h3>

Answer:
x=2
Step-by-step explanation:
add 3 to each side to isolate the 3x alone on one side
3x=6/ divide by 3 to isolate and simplify
x=2
