Step-by-step explanation:
We are given a statement that:
Everyday luis buys 5 more baseball cards to add to his collection . if he has 25 baseball cards before making any purchases.
We are asked to find how many will he have on day 20?
Let denotes the number of baseballs cards on nth day.
on the first day he will have:
on second day he has:
On third day he will have:
and so on on the nth day he will have:
We are asked to find the number of baseball cards on 20th day.
i.e. n=20
Hence, on the 20th day he will have 125 baseball cards.

Answer:
This Is CORRECT
Step-by-step explanation:
The solution of the system of equation is the intersection point of the two quadratic equations, so we need to equate both equations, that is,
So, by moving the term -3x^3+20 to the left hand side, we have
Then, in order to solve this equation, we can apply the quadratic formula
In our case, a=5, b=-3 and c=-30. So we get
which gives
By substituting these points into one of the functions, we have
and
Then, by rounding these numbers to the nearest tenth, we have the following points:
Therefore, the answer is the last option
Solution:
we have given the length of the rectangular card-
and, width-
now, the area of the card will be- length×width.
so, we have-
we also have given the length of ribbon-
and, width-
so, area of the ribbon is-
length×width
now the area of shaded gray region will be-
Hence, the required expression would the above expression.
