A fraction a/b consists of a numerator (the part above the bar, a in this example) and a denominator (the part below the bar, b here). In order to add or subtract fractions, we need to make sure the denom...

This can't be integrated directly as y appears in the numerator and denominator. This is an indication that you must integrate by parts. A/y + B/(3y+2) = (3y - 4)/y(3y + 2) A and B must be found. Multiply...

Area Scale Factor = (Scale Factor)²

If the scale factor is 3 then:

ASF = 3²

ASF = 9

Area of enlarged rectangle = 20x9

Area of enlarged rectangle = ...

m = 2ab/4c+b [times both sides by (4c+b)]

m(4c+b) = 2ab (expand the bracket)

4cm+bm = 2ab (take away bm from both sides)

4cm = 2ab - bm (take out b as the common factor)

4cm = ...

1. Find the gradient of line L. The gradient can be defined as the "change in y" divided by the "change in x". For this situation, the "change in y" would be 9 - 3 = 6. Th...
