    I'm afraid that can't be solved - have you posted the diagram properly? You need some indication of the height of the line in the shape.

    OK - sorry I see - there are are options - I thought you need to solve for x It is obvious the the line is longer than 15, and less then 27 which value from your options evaluates 4x+5 to between those values?

    if x was 21 (answer d ) then 4x+5 = 4*21 + 5 = 89 this is too long so it cannot be d do the same with the other 3 answers and see which gives an answer between 15 & 27

    sorry - correction: OK - for answer a you got 4*2 + 5 = 13 that is correct - but if you look at the drawing the line MUST be longer than 15 so 2 cannot be the answer you need to try the other possible answers until you get a value between 15 and 27

    No thats not what happened i got 4*2+5 = 13, 4*4+5=21, then my other answer is 4*8+5=37
