Firstly we have an equation y=4x-6. We are given that x=3 and we want to find y. What we must do is substitute x=3 into the equation to get y: y=4(3)-6 =6

First, multiply out 6x(x^2 - 3) so that it becomes – 6x^2 – 18xThen, multiply (3x^2 + 2) and (2x + 5) so that it becomes 6x^3 + 15x^2 + 4x + 10Add the two results above: 6x^3 + 15x^2 + 4x + 10 – 6x^3 – 18...

Use the formula (n-2)*180 where n is the number of sides on the polygon.

If two lines are parallel, then they will have the same gradient. The gradient of the curve is represented by m in the equation y=mx + c. For this question, if L2 is parallel to L1, m will therefore equal...

4(3x-2)=2x-5
Expand the brackets: 4(3x)-4(2)=2x-5 ---> 12x-8=2x-5Collect like terms, but beware of sign changes: 12x-2x-8=-5 (subtract 2 from both sides of the equation) -----> 10x...
