There are 20 total cubes.
7/20 + 5/20 = 12/20 = probability that the cube WILL be blue or red. Can be reduced to 3/5
Therefore, the probability that the cube will NOT be blue or red is 8/20 or 2/5.
(x-1)^2-4
If u put the vertex into vertex form you get this answer.
B;
A monomial is a single term;
All the others apart from option B have two different terms being added together.
An expression which has no addition or subtraction can be classified as a monomial if I'm not mistaken.
7y + 3y = 180
10y = 180
y = 180/10
y = 18
so < 9 = 7y = 7(18) = 126
< 10 = 3y = 3(18) = 54
< 9 and < 11 are corresponding angles....so they are equal....so < 11 is 126 degrees....< 11 and < 16 are vertical angles...so they are equal....so < 16 is 126 degrees <==
