(6x^2+4x-15x-10)(x+7)(6x^2 -11x-10)(x+7)= 6x^3-11x^2-10x+42x^2-77x-70)=6x^3+31x^2-87x-70

Put all the terms which contain x onto one side of the equation.-6 from both sides of the equation and -18x from both sides of the equation to get7xy-18x = 3y+7-6Simplify if possible7xy-18x = 3y+1Take the...

First, check you understand what the question's asking by determining the key words. Next, try a couple of examples to convince yourself that the statement does in fact work, i.e 1+2+3+4=10, which is even...

Pi is the ratio between a the circumference and the diameter of a circle. It's just a number which happens to describe this ratio for any circle you can think of. Let me explain, using the whiteboard...

In a proportional equation, you represent the factor of proportionality as k. In this case it means that y=kx^2. In the question you're given a number for both y and x. Sub these in in order to solve for ...
