The difference between two numbers is 9.
laiz [17]

Answer:

first number=15 second number=6

Step-by-step explanation:

lets take the first and second numbers as "a" and "b"

a-b=9

a+2b=27  (solve these equations simultaneously)

eliminating a

-3b= -18

b= 6

then substitute in the first equation

a-6=9

a=9+6

a=15

I really hope you know how to solve equations simultaneously

hope this helped

Water flows from the faucet at the rate of 5 L every 25 seconds at this rate how much water will flow from the faucet in 45 seco
Citrus2011 [14]
5L:25Seconds=1L:5seconds
In 50 seconds there will be 10L of water
In 45 We will have to subtract 1L because we are exceeding 5 seconds and in 5 seconds 1L of water comes out
10L-1L=9L
There will be 9L of water

42 point Plus brainliest slove it g(x) = (x + 2)(x − 1)(x − 2)
Dmitry_Shevchenko [17]

Answer:

x = -2,1, 2

Step-by-step explanation:

g(x) = (x + 2)(x − 1)(x − 2)

Assuming we are looking for the roots

0  = (x + 2)(x − 1)(x − 2)

Using the zero product property

0 = x+2    0 =x-1    0 = x-2

x=-2         x = 1            x =2
