To find the value of
, we need to isolate it on one side of the equation. Add
to both sides of the equation, then multiply both sides of the equation by
.

Answer:
They both have area 4
Step-by-step explanation:
Area of the square:

Area of the triangle:
Using the left-side of the triangle as the base, and the height from the left-side to the bottom-right corner:


We know the length of the diagonal is
as we are using a centimetre grid, so we can create an isosceles triangle with side lengths 1 and our unknown length, we can then use Pythagorean Theorem to work out our unknown side length.




Answer: The net change would be -2.
Step-by-step explanation: The upward change of elevator is represented by positive sign while the downward change represented by negative sign.
Given, First the elevator goes up 15 floors, change = + 15, Then it goes 9 floors down, change = -9, Then it goes 11 floors up,Change = + 11, Finally, it goes 19 floor down, Change = - 19 So, the net change = sum of total changes = 15 - 9 + 11 - 19 = -2
