Qr=1/2 mn = ms
mn=2 ms=12
ln^2=lm^2+mn^2 using phythagoras rule
ln^2=400
ln=20
First replace the x
X=3
2x3 to the power of 2
Then solve
2x3= 6
6 to the second power is 36 (6x6)
Answer 36
Answer:12 packs
Step-by-step explanation:4.5x4 is 18 then u divided 4.5,3 times to make 1.5 after that 3x4=12 or you could divide 18 by 1.5 and get the same answer
5.
6 / t = 9 / (t+2)
9t = 6t + 12
3t = 12
t = 4 answer
The remaining length:-
6 / 4 = 11 / x
6x = 44 so x = 7.33 answer
6. 8 / w = 6 / (w - 5)
6w = 8w - 40
2w = 40 so w = 20 answer
The side marked w - 5 = 20-5 = 15 answer
8/14 = 20/x giving the top side = 35 answer
