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.

An Internet store charges a base fee plus $1.50 per pound to ship items. The table shows samples of their shipping rates.
nalin [4]

Answer: For Last Question 4.50

Step-by-step explanation:It depends on the price per pound. Let's say the price per pound is 50 cents (or 0.50). (This is an example, the answer I'm giving will most likely NOT be correct, due to the nature of your question - sorry!) To calculate the price of Derek's package, you would multiply 7 (the weight of the package) by 0.50 (the price per pound), which totals to 3.50 Next, to calculate the price for Keisha's package, you'd do the same thing, but instead of multiplying 7 by the price per pound, you would multiply 10 by the price per pound, or 0.50. This multiplies out to 5 dollars. Next you'd subtract Derek's price from Keisha's, which is 5 - 3.50 or 1.50. If it is asking for a percentage, it would be about 150%.
