Lena says that 4xy^3 and -5x^3 y are like terms. Is she correct? Why or why not? A. Yes, because both terms have a variable with a power of 3 and a power of 1. B. Yes, because both terms have an x and a y. C. No, because the same variables are not raised to the same powers. D. No, because the two terms do not have the same coefficients.

i think there was a typo. you wrote pat brings 3 quarts of ice-cream to the party. each serving of ice-cream is 1 6 quart. how many total servings of ice-cream does pat bring to the party? i think the bold is supposed to be 1/6. so 1 quart of ice cream = 6 servings. 6 * 3 = 18.

\3. yes the presentation (i.e. odd numbers being written as differences of two squares) is possible for all odd natural number however the presentation may not be unique. for example,  57=112−82=292−28257=112−82=292−282.

\4. 2 can't be written as a difference of two squares because 4-1=3 and 1-1=0 and the difference of squares grows to integers larger that 3.

can i get some in proving questions 1 and 2?
