the ratio given is 5:2simplify this ratio by diving 2 = 2.5 : 1
the maximum amount of blue paint is 9Lso multiply the whole ratio by 99 x 1 = 9.0L blue paint9 x 2.5 = 22.5L red paint add the two pai...

First, the numerator and denominator of the fraction need to be factorised:(x+3)(x-2)/(x-5)(x-2)The 'like' terms should then be crossed out; in the case above, it is the (x-2) brackets.(x+3)(x-2)/(...

6x² + 7x - 3

2x² + 7x + 6 step 1: find 2 numbers which times to make 12 and add to make 7, ans 3 and 4 step 2: rewrite equation as follows. 2x² +4x +3x +6step 3 factorize into: 2x(x+2) + 3 ( x+2)...
