VERY EASY QUESTIONMadison made a mistake when she combined terms. Explain what Madison did wrong? Explain and give an example of what she should have done.

Answers

Her mistake is that she didn't distribute the terms correctly . She subtracted 4 and- 2x , which is incorrect . She had to multiply -3 and the numbers inside the parenthesis .

the mistake is in combining 4 with -2x because they're not like terms

In at least 100 words independently write your response to the statement, "Anyone can do well in math."

Answers

Answer:

I believe that this is true. Anyone can do well in math, not everyone. The main difference being that if EVERYone could, that means every one person in the world, no matter the circumstance, so by saying ANYone, it's saying that however many people in the world want to do it, can do it, if they try and put in the work. Math is not biased against any one person, nor is it favored for any one person. Any person who studies, or learns it can do well in math. Someone who has never learned anything about math will not do well at all. So, yes, ANYone can do well, but not EVERYone.

Not 100 words, but should do trick if you just add in some extra words between phrases, and substitute some words with one or two synonyms.

Answers

so you need to know that
1pound=16ounches
1oz=1ounce
1ton=2000pounds=2000 times 16=32000oz

therefor just divide

134893oz/16=pounds=8430 and 13/16 pounds or 8430.8125 pounds
to find tons, just divide the pounds by 2000
8430.8125/2000=4.21541 tons

134893oz=8430.8125 pounds=4.21541 tons

What must be added to
2x² - 3 xy + 5yz to get x² - xy + y²

Answers

Answer:

-x² + y² + 2xy - 5yz

Step-by-step explanation:

"A" must be added to first expression to get the second one:

A + 2x² - 3 xy + 5yz = x² - xy + y²
A = ?

------------------------

A = x² - xy + y² - (2x² - 3 xy + 5yz) =
x² - xy + y² - 2x² + 3 xy - 5yz=
-x² + y² + 2xy - 5yz
