Do you know which side is the hypotenuse in a right angled triangle?
Can you work these out or explain them so I understand:
Factorise:15ab + 3b
24mn – 6n
Solve: 6w + 9 = 18w – 3
5(2d +3) = 35
Thanks so much!

The hypoteneuse is the long side of the triangle
15ab + 3b, factor out 3b to get 3b(5a + 1)
24mn - 6n factor out 6n to get 6n(4m - 1)
6w + 9 = 18w - 3
12 = 12w
divde both sides by 12
w = 1
2d + 3 = 7
2d = 4
d = 2

Factor:
First remove the b since it is present in both terms
b(15a+3)
3 can go into itself and 15 so remove that
3b(5a+1) - Answer
Solve:
5(2d+3)=35
Multiply 5 to the term is is attached to
10d+15 = 35
Subtract 15 from both sides
10d=20
divide both sides by 10
d=2

1) the side opposite the right angle
2) 3(5ab+b) 6(4mn-n)
6w+9=18w-3
9+3=18w-6w
12=12w
w=1
5(2d+3)=35
10d+15=35
d=(35-15)/10
d=20/10
d=2

1) the side that is the longest
2) 3b(5a+1)
6n(4m-1)
3) 12=12w ; 1=w
10d+15=35 ; 10d=20 ; d=2

the triangle - the longest side
15ab + 3b = 5 * 3 * a * b + 3 * b
24mn - 6n = you got to do that, i dont know how on the keyboard.
what ever

3b(5a+10
6n(4m-1)
12=12w
w=1
10d+15=35
10d=20
d=2

which ever side is the base. it's like the longest side. I think it's whatever # is c. I don't know but i think that's it. i can't tell u which # that is though.
