Answer:
51 were the total number of the tickets sold at a school carnival were early-admission tickets.
Step-by-step explanation:
Total number of tickets sold by = 100
Let
be the early-admission tickets sold by the school.
As 51% of the tickets sold at a school carnival were early-admission tickets.
so


Therefore, 51 were the total number of the tickets sold at a school carnival were early-admission tickets.
Let the measure of angle be 'x'
Since, the measure of the supplement of an angle is 84° less than the measure of the angle.
Therefore, measure of supplement of x = x - 84°
The measure of two supplementary angles is 180 degrees.





So, the measure of angle =
Its supplement = x - 84° = 132° - 84°
= 48°
So, the measure of supplement of angle is 48 degrees.
I believe is A :)

Answer:
The coefficient of y² will be 1, which we can see when we expand the expression:
(x + y)²
= (x +y)(x + y)
= x² + xy + xy + y²
= x² + 2xy + y²
