A monomial is an expression with one term (ex: x, 5y, 6z, 8wxy, b²)
A binomial is an expression with two terms (ex: 4 - 6y, 5x + 2z, 3w + 7, xyz + abc)
A trinomial has three terms
A constant is a term with no variables - a number, in other words, like 3, 4, 154, 78, etc.
The expression 12xyz - 45 has two terms, 12xyz and 45, making it a binomial.
Answer:
k=16
Step-by-step explanation:
k/4 - 1 = 3
Add 1 to both sides
k/4 = 4
multiply both sides by 4
k = 16

Step-by-step explanation:
Answer:
∠ AOB = 139°
Step-by-step explanation:
Since AOC is a straight line then
∠ AOB + ∠BOC = 180° , that is
8x + 51 + 6x - 25 = 180
14x + 26 = 180 ( subtract 26 from both sides )
14x = 154 ( divide both sides by 14 )
x = 11
Then
∠ AOB = 8x + 51 = 8(11) + 51 = 88 + 51 = 139°
