    the last question was very easy, all you got to do is to minus the big triangle by the small triangle but you gotta put it in surd form though

    For question 12 I incorrectly simplified the answer to 75 pi instead of 100 - 25 pi. How many marks would this lose me? I did write the correct answer above my answer, but just simplified it wrong

    was it not 100-25 TT all divided by 4?

    no, because after you subtract the area of the circle from the square, you are left with those 4 segments (the shaded area). so 100-25 TT gave the combined area of those 4 segments

    But you've got to multiply that by 0.7 from evaluating 3.5/5. Since 0.7x10^9 isnt standard form you get 7x10^8
    ah, I see

    well, thank you for the explanation

    tfw you can't math :^(

    It asked for it in it's simplest form which is 25(4-pi). However on the unofficial teacher mark scheme s/he left it as 100-25pi.

    The question said the rent was raised by 20% from 30% so you had to find 20% of 30% which is 6%. You thenn add the 6 back onto the original 30 to get 36%
    That's the same as 120% of 30 lol...

    For the X^2=4(X-3)^2 i got 3 but i dont think thats right...

    No, x = 2 or 6. Explained in detail below.The right hand side of the equation expands to:

    x^2 = 4x^2 - 24x + 36.

    Then subtract x^2 from both:

    0 = 3x^2 - 24x + 36

    Divide both sides by 3:

    0 = x^2 - 8x + 36

    The right hand side factorises:

    0 = (x-6)(x-2)

    Therefore, x = 6 or 2


    To prove this, sub them back in:

    6^2 = 4(6-3)^2
    36 = 4(9) which it does, and

    2^2 = 4(2-3)^2
    4 = 4(-1)^24 = 4(1) which it does
