Expand and simplify: (5w-6)(2w+7)

So first you need to multiply out the brackets so you can simplify the equation. Remember the acronym FOIL: First, Outer, Inner, Last.10w^2 + 35w - 12w - 42
And then you need to simplify
10w^2 + 23w - 42

Solve the simultaneous equations: y=x^2 + 3x + 7 and y=x + 10

Re-arrange (3x+y)/2 = x+z making x the subject.

A cuboid has length x cm. The width of the cuboid is 4 cm less than its length. The height of the cuboid is half of its length. The surface area of the cuboid is 90 cm^2 . Show that 2x^2 − 6x − 45 = 0
