The standard equation of a circle is in the form (x-a)^2+(y-b)^2=r^2, where the coordinates of the centre of the circle is (a,b) and the radius of the circle is r. Therefore, you must put the given equati...

To begin a stem and leaf diagram you will need to first order the data given to you into the question. The data in your stem and leaf must be in ascending order and grouped into tens. Draw the table separ...

Firstly, multiply the whole equation by (4 - a) to cancel out the denominator, so the equation becomes: p(4 - a) = (3a + 5). Then expand the brackets: 4p - ap = 3a +5. Then rearrange the equation to: 4p -...

First start by considering the x⁰ coefficient which is -3. These include ±3 and ±1. Substituting x=1 into the polynomial produces an answer of 0 which shows that x=1 is a factor of the polynomi...

To understand the question, we have to know what a third is. 1 is made up of three thirds (3/3 presented in a fraction), so in order to obtain 9 we must multiply it by 3. The answer is 27.
