This is a system where (f-g)(x) is wanted.
(16x-30)-(14x-6) .... 2x-24 *be careful with signs and parenthesis placement.
Now set 2x-24 = 0 and so x = 12
Answer:

round off to 3s.f
means change to when you have 3 useful numbers
7613.83 has 4numbers.2decimal
same must be the round off value
Y= -2, -1, 0, 1 ,2
The function is linear
264 because you can do 8 divided by 6 and get 1.3 repeating, than you would do 198 times 1.333333333333 and you get 264
The Volume of PYRAMID A is 8 times greater than the Volume of PYRAMID B as obtained by taking the ratio of the volume of both pyramids.
Volume of a square based pyramid is given as :

Where; h = height ; a = base edge
Hence, Volume of PYRAMID A :

Volume of PYRAMID B = 3,136 in³
Divide Volume of pyramid B by pyramid A :

= 8 times
Expressing as a percentage, multiply by 100% ;
8 * 100% = 800%
Therefore, The volume of PYRAMID B is 800% times GREATER THAN that of PYRAMID A.
