The answer is
AB = 6.
External value x (external value + internal value) =
External value x (external value + internal value) of the other side
Substitute, transpose, and simplify.
TA x (TA + AB) = TC x (TC + CD)
10 x (10 + (x + 2)) = 8 x (8 + 12)
120 + 10x = 160
10x = 40
x = 4
To find AB: x + 12; x = 4
AB = x + 2
AB = 4 + 2
AB = 6
For this problem, you have to find the g(x) right?
The f(x) is already given, so all you have to do is multiply both sides by negative 1 (-1) to get the g(x) which is the opposite.
It'll look like this (g(x) = x^2 + 3x + 2)(-1)
Then the answer should be, g(x) = -x^2 - 3x - 2
Answer:
positive 48 ..yan yung pagkakaalam ko
So there are 10 offices in the first 2 floors
All the stories of the building have the same amount of offices on each floor
to see how many are on one floor
10 / 2
That is there are 5 offices on each floor
If there are 5 floors
then... 5+5+5+5+5
or 5*5
There are a total of 25 rooms in a 5-story building.
Hope this helps :)
