Hi there!
Answer:
A. 7x² - 9x - 5
Step-by-step explanation:
If you simply take away the parentheses, you get:
3x² - 4x + 7 + 4x² - 5x - 12
Then, just add them all together, and you get:
A. 7x² - 9x - 5
Let me know if you have any questions!
I'll do a similar problem, and I challenge you to do this on your own using similar strategies!
Take y > 7x+2
Plugging in the origin, we have (0,0) as our points, and 0 > 0*7+2=2, so 0>2. As 0 is not greater than 2 (less than is the way that it's pointing), this is false. In addition, as it is y greater than 7x+2, the shaded area is above the line due to that y is greater than, and since y is up and down, greater than means higher than.
Good luck, and feel free to ask any questions that come up!
Answer:
There are 60 green paper clips.
Step-by-step explanation:
if 2/3 of the box = 120 clips, then you can determine that 1/3 is 60, since 1/3 is half of 2/3. If 1/3 is 60, Since you already know that 2/3 is 120 clips, you add 60 to get 180 total clips, and 60 of them are green.
Answer:
To subtract two or more monomials that are like terms, subtract the coefficients; keep the variables and exponents on the variables the same
Step-by-step explanation:
A monomial is a number, a variable or a product of a number and a variable where all exponents are whole numbers. That means that
42,5x,14x12,2pq
