The water level in ricky lake changes at an average of -7/48 inch for 1 year.Based on the rate above how much will the water lev
bearhunter [10]

we are given

The water level in Ricky lake changes at an average of -7/48 inch for 1 year

It means that

In 1 year , the water level changes at \frac{-7}{48} inches

and we have to find the water level change after 5 years

so, we can multiply both sides by 5

In 5*1 year , the water level changes at 5*\frac{-7}{48} inches

In 5 years , the water level changes at \frac{-35}{48} inches

Hence,

the water level change after 5 years is \frac{-35}{48} inches........Answer

Urgent help! This is very important please help me fast! How do you do: Expand & simplify:(x 4)(x 2)
ahrayia [7]
So the question is asking: (x-4)(x-2)
because there is a bracket in between the two expressions it means we have to multiply them together: (x-4) x (x-2)

you can break down the question into smaller parts:
x multiply x
x multiply -2
-4 multiply x
-4 multiply -2

here are the answers:
x^2 (means x squared)
-2x
-4x
8 (because when you multiply two negative numbers it makes a positive)

now you put it into an expression (this is expanding):
x^2 - 2x - 4x + 8

to simplify it you collect like terms:
x^2 - 6x + 8

The above is the answer :)
