The first thing we should note here is that we are looking for the area, so we need to recall the formula for the area of a right-angled triangle:
Area = (base x height) / 2Answered by Kirsty S. • Maths tutor11278 Views
This is an example of a linear equation. To find x we can apply the same operations to both sides in order to isolate x.First we can subtract 6 from both sides.This gives us 4x on the le...
To rearrange a formula, it is required that you group variables in certain ways, to leave you with the desired form.
For example,
Rearrange y=3x^2+3 to make x...
