Question

PLEASE HELP!! (Question in picture) For BRAINLIEST and more !!

Answer 1

Like terms are terms that have the same variable no matter the coefficient value such as a negative or positive coefficient (number right to left of the variable aka the letter representing an unknown amount of value).

A. 8n : - 4n becuase the have the same variable (N)

B. - 2d: D because they have the same variable and even if d has no coefficient, it still has value, variables with no coefficient always equal 1 no matter the circumstances

C. - b: 17b and -3b2 because they both have the same variable eliminating the coefficients being two different types of numbers (positive and negative). The expressions have to have the same variable.

D: 4y², -3y2,4y, and 4 to the second power. This is because they all have the same variable.

E. 6x2y: 3xy because the variable are specifially xy and they must be in order to be like terms.

abc: all because they have all the letters but are just in different orders of variables. (thats all)
