What is the like term for 4m+(-3n)+n? what is the like term for c+2c+c-5c+1

a) The three terms have variables m, n, n. The two like terms are the last two terms, which both have variable n: -3n, n.

b) The 5 terms have variables c, c, c, c, -. The like terms are the first four, which all have variable c: c, 2c, c, -5c.

x = ± 6i

step-by-step explanation:

x^2 = -36

take the square root of each side

sqrt(x^2) = sqrt(-36)

we know sqrt(ab) = sqrt(a) sqrt(b)

x = ±sqrt(36) sqrt(-1)

we know that sqrt (-1) = i

x = ± 6i
