One expression you can do, is to simply simplify the expression,

We can deistribute the 3
6n+9+9

You can then simplify further:
6n+18

Once we have the simplified expression, you can then expnd it in different ways for example:
3(2n+6)

Hope these helped!

Thethree sides of a triangle measure 810 and 12 units is this a right angle?

Alja [10]

Answer:

The given triangle is NOT A RIGHT ANGLED TRIANGLE.

Step-by-step explanation:

Here, the three given sides of the triangle are:

8 units, 10 units and 12 units

Now, for any triangle to be a right angle:

by the PYTHAGORAS THEOREM:

$(Base)^2 + (Perpendicular)^2 = (Hypotenuse)^2$

The longest of all sides id the hypotenuse.

⇒ H = 12 units

Let us assume, B = 8 units, P = 10 units

Now, here checking the condition:

$(8)^2 + (10)^2 = 64 + 100 = 164 \neq (12)^2 = 144\\\implies (B)^2 + (P)^2 \neq (H)^2$

Hence, the given triangle is NOT A RIGHT ANGLED TRIANGLE.
