So imagine these are all things so u have
3pencils
4rulers
7erasers I say rubber cause I’m British
1 pencil
8 rulers
And 1 rubber

X and xsquared are two different things so you cant add them or subtract
And single numbers two

So add 3x squared to x squared (or 1 xsquared same thing) u get 4x squared

Then u minus 8x from 4x and get -4x
Then you subtract -7 from -1 and get -8
Then you write them together like 4x squared + -4x -8

There if u need any more help I’m open

i) first you combine the like terms; 3x² and x², then 4x and -8x, then -7n and -1.

Then you would get 4x²-4x-8.

You then cannot simplify further. so your answer would be 4x²-4x-8.

Given the function f(x) = √x-8 + 3 which of the following is the value of f(24)
kvasek [131]

Answer:

The answer is 7.

Step-by-step explanation:

You have to substitute the value of x into the function :

f(x) =  \sqrt{x - 8}  + 3

f(24) =  \sqrt{24 - 8}  + 3

f(24) =  \sqrt{16}  + 3

f(24) = 4 + 3

f(24) = 7

slamgirl [31]

Answer:

The rate is \frac{1}{6} cups per hour

Step-by-step explanation:

It took the faucet 1 1/2 hours equivalent 3/2 hours to fill 1/4 cup by leaking

We need to find the rate in terms of cups that can be filled by water in 1 hour.

Using unitary method:

it takes \frac{3}{2} h for \frac{1}{4} cup

it will take 1 h for how many cups?

= \frac{1 \times \frac{1}{4} }{\frac{3}{2} }= \frac{2}{4 \times 3}= \frac{2}{12}= \frac{1}{6} cups

Hence, the rate is \frac{1}{6} cups per hour
