Answer:

It doubles the area.

Step-by-step explanation:

The formula for the area of a triangle is a = bh/2. So, if we plug in the first triangle, you get a = 6. With the second triangle, the height is being doubled. We can represent this with the equation:

4 × 3 × 2/2

Both 2s cancel each other out, leaving us with a = 12. 12/6 is 2. Therefore, doubling the height will ALWAYS double the area.

Please help me with these two questions. And can you tell me how to do this! Thanks you
Vaselesa [24]
(X-10)(X-10) You need to first multiply out the brackets. So, first times X by X, which makes x^2 . Then do -10 x -10 which makes 100. You then need to multiply the X within the first bracket with the minus 10 in the second bracket which makes -10x. Do the same but with the -10 from the first bracket and the X from the second which again makes -10x. So altogether you have x^2-10x-10x+100. This can be simplified down to x^2-20x+100. You then do the same thing for the second question :)
