X+2 or x+2=y. X would be Luke’s age and if you add 2 years you would get Ellen’s age (y). Hope this helps.
Answer:
94 seats
Step-by-step explanation:
We solve using Arithmetic sequence formula
an = a + (n + 1)d
Where
a = First term = 49
d = Common difference = 52 - 49 or 55 - 52 = 3
n = 16th row
Hence,
a16 = 49 + (16 - 1)3
a16 = 49 + (15 × 3)
a16 = 49 + 45
a16 = 94
Therefore, the number of seats on the 16th row is 94 seats
Answer:
The last choice.
Step-by-step explanation:
The last term is - 20 and because we have a coefficient of 1 on the x^3, and in order to get this last term and the given roots the factors have to be
(x + 5)(x + 4)(x - 1) so it is the last option.
