Answer:
Step-by-step explanation:
So the Dimensions are:
Height: 300cm
Length: 300cm
Width: 2cm
SA = 2(H*L)+2(H*W)+2(L*W)
= 180000 + 1200 + 1200
= 182400 
OR 18.24
Answer: (i) 2/6=0.33 and (ii) 4/6=0.66
Explanation: if you were to add everything up there would be 17 boys and 17 girl and then you would end up with 6 people who write with their left hand and 28 people who right with their right hand. I hope this helps
Well for 3. you use the Pythagorean theorem to say that 28^2 - 18^2= x^2 so 21.4 and for 4. the Pythagorean theorem says a^2 + b^2 = c^2 with c being the hypotenuse of any right triangle so the sums of the two smaller squares make the sum of the larger square making the answer b
Answer:
9x^2-9x-3
Step-by-step explanation:
3x*3x=9x^2
3x*-4=-12x
1*3x=3x
1*-4=-3
9x^2-12x+3x-3
9x^2-9x-3
