Answer:
1.) no. of terms = 3
terms = 7x², 3x, -9
numerical coefficient = 7, 3
variable = x
constant = -9
like terms = none
degree = 2nd degree
2.) no. of terms = 4
terms = 18x^3, -4x², x, -10
numerical coefficient = 18, -4, 1
variable = x
constant = -10
like terms = none
degree = 3rd degree
3.) no. of terms = 5
terms = 4x², -8x, 9x², 10x, 20
numerical coefficient = 4, -8, 9, 10
variable = x
constant = 20
like terms = (4x², 9x²) and (-8x, 10x)
degree = 2nd degree
4.)
5.) no. of terms = 4
terms = 3x², -2z², -11x², 14x²z
numerical coefficient = 3, -2, -11, 14
variable = x, z
constant = none
like terms = 3x², -11x²
degree = 2nd degree degree
