Please help Anyone
@mathmate @welshfella Can you guys help? I have a general idea of what I need to do for part one, but I get really lost afterwards.

square of hypotenuse , by Pythagoras theorem = sum of squares on the other 2 sides = (x - 7^2 + (2x - 10)^2
I got that much, but I need to simplify it I believe
What do you have that you need to simplify?
I need the square length of the hypotenuse. so wouldn't I need to simplify (x-7)^2 + (2x+10)= C^2?
Like I know that much but I don't know what to do afterwards. do I square everything?
You need to square (x-7) and (2x-10) right now. If you have a scientific calculator you can do this easily, but if you have a reg. calculator then do (x-7)(x-7) and use the distributive property. Then do the same with (2x-10)(2x-10)

Did I do that part correct?
h/o
Oki cx
Yes that's right :) sorry if I'm slow to respond I'm doing my exam
Okay, so now I do (2x-10)(2x-10)?
Yep
|dw:1433177671889:dw| Sorry for the bad writing ;-;~
now had these 2 expansions together x&3 - 14x + 49 + 4x^2 - 40x + 100
**correction first term is x^2
add them?
yes
|dw:1433178085721:dw|
add like terms eg x^2 + 4x^2 = 5 x^2
yep
is that the answer? for part A I mean
yes
Part B the area = 1/2 * base * height = 1/2 * (x - 7) (2x - 10)
how do I do that o.O
@kobeni-chan ? ;-;~
to make it easier 1/2 * (2x - 10) = (x - 5) now work out (x - 7)(x - 5) and you gave the required area
* have

@welshfella can you please help me
I'm so sorry I got very busy and forgot about your question :( what part are you on?
Part B I believe >.>
Ok so Pt. B is asking the area.. what is your understanding of this Q?
That for the area, you need to do a=1/2*b*h since we already have b and h, we just plug it in. Right?
Yup!
I got that much, but when it comes to trying to find said area, I get completely lost
\[1/2*(2x-10)(x-7)\] is your equation
I know that much, but I don't know how to apply the 1/2 to the (x-7)
you've worked it out correctly alice
so is that trinomial the Area?
You can either take it's inverse out, but since it's an expression & not an equation, it's like dividing (x-7) by 2.
apply the half to (2x -10) first makes it easier 1/2 * (2x - 10 ) = x - 5
^ Agreed
so it comes down to (x -5)(x - 7) which you worked out correctly in an earlier post alice
I did (x-5)(x-7). Is there no other step afterwards?
Nope. You can check your work by multiplying again, and you should be getting the same answer you started with.
