Polynomial means more than 1 term when all like terms are combined
terms are seperated by plus or minus symbols
you can't combine placeholders and numbers
y is 1 term, not poly
4x^3+y is 2 term, poly
2+s is 2 term, poly
answer is 4x^3+y and 2+s
cubic means highest power of the placeholder is 3
quadratic means highest power of placeholder is 2
trinomial means 3 terms
yep, 3 terms
4x^2+3x+5
highest power is 2
quadratic trinomial
Answer:
Upper level = 2502 seats
Middle level = 5044 seats
Lower level = 7456 seats
Step-by-step explanation: given that
A baseball stadium holds 15,002 seats.
Let the Upper, middle and lower levels be represented as U, M and L respectively. And x = number of seat at the upper level
The lower level has 50 fewer than three times as many seats as the upper. That is
L = 3x - 50 .... (1)
The middle level has 40 more than twice as many seats as the upper level. That is
M = 2x + 40
Where L = x
x+ (2x + 40) + (3x - 50) = 15,002
You solved for x and found out the upper level has 2,502 seats . How many seats are in the lower level and how many seats are in the middle ?
That is x = 2502
Substitute x into equation 1
L = 3(2502) - 50
L = 7456 seats
Substitutes x into equation 2
M = 2(2502) + 40
M = 5044 seats
You can either solve this with the Pythagorean theorem or the special triangles rule which can be applied to (degrees —>) 45/45/90 or 30/60/90 triangles.
With the Pythagorean theorem: a^2 + b^2 = c^2 is used with the numbers accordingly- 5 and S are legs and can be either a or b while √50 being the hypotenuse can only be c
(5)^2 + (s)^2 =(√50)^2
25 + (s)^2 = 50
√ ((s)^2) = √ (50 - 25)
s = 5
The special Triangles rule actually states that a shortcut can be applied to the corresponding sides (look at picture). S is directly across from a 45 degree angle (and so is 5!)
If a = 5, than s must also = 5.
3/5 • 4/5 = 12/25.
This would be the solution to the above question, simply multiply both the numerator and denominator together to get the final answer.
