Factor.
3g2+ 25g + 8
please put it at (x+b) (x+b) form

(3g + 1)(x + 8)

Step-by-step explanation:

3g2+ 25g + 8; think of FOIL

(3g + ___ ) (g + ___); you know you will get the first term when you multiply 3g and g.  Also you know that the signs will be positive because 25g and 8 are positive.

Now think of the multiples for 8 because it will be the last term; it could be 4*2 or 8*1 and move the options so you get 25g from outers and inners.  You will get this

(3g + 1)(x + 8)

none of the above.

for one of the equations to be used in the process, there has to be a term in the equation since squared is .

since there is only a term in the first equation, we cannot derive a from completing the square.

solving with completing the square

step-by-step explanation:

12: 00 p.m. to 7: 00 p.m. is a total of 7 hours.

4: 00 p.m. to 7: 00 p.m. is a total of 3 hours.

this means that from 4: 00 p.m to 7: 00 p.m. this represents 3/7 of what was lost from 12: 00 p.m. to 7: 00 p.m.

after knowing this, after doing 11,600 - 6,800 = 4,800

4,800 represents 3/7 of what was lost for 7 hours.

we then divide 4,800 by 3 which gets 1,600.

because we know that 1,600 represents 1/7 of how much water was lost, we just have to multiply by 7, which gets 11,200.   after adding 11,200 to how much water was left at 7: 00 p.m. which was 6,800. 11,200 + 6,800 = 18,000

this means that the pool originally had 18,000 gallons in the pool.

you can also check your work by doing 18,000 - 4(1600), which becomes           1800 - 6400 which gets you 11,600.
