Answer:

6y - 8

Or

2(3y - 4)

Step-by-step explanation:

The given expresion is 2y-8+4y.

We want to find an expression that is equal to 2y-8+4y.

We need to group like terms to obtain:

2y + 4y - 8

We can now combine the like terms to get:

2y + 4y - 8

6y - 8

We can factor 2 to obtain:

2(3y - 4)

A rectangle has a height of 3n^2 and a width of 4n^2-5n-1.
Galina-37 [17]

Answer:

A = 12n^4-15n^3-3n^2

Step-by-step explanation:

The dimensions of a rectangle are length and breadth/width

Here we are given height . Assuming it to be one of the side of the rectangle , we will do the further calculation

Hence one side is

side 1 = 3n^2

And the other side is

Side 2 = 4n^2-5n-1

The area of rectangle = side 1 x side 2

A=3n^2 \times (4n^2-5n-1)

A=3n^2 \times 4n^2-3n^2 \times 5n-3n^2 \times 1

A=3 \times 4 \times n^2 \times n^2- 3 \times 5 \times n^2 \times n - 3n^2

A = 12n^4-15n^3-3n^2

Hence area can be given as expression

A = 12n^4-15n^3-3n^2

Olivia is going to an amusement park. The price of admission into the park is $40, and once she is inside the park, she will hav
svetoff [14.1K]

Answer:

Cost for 13 rides: $92

Cost for r rides: I am guessing it would be 40+4r

Step-by-step explanation:

If you automatically pay 40 dollars to get in, then that is the constant, and paying 4 dollars per ride is a coefficient, so that would be multiplied by how many rides you go on, the variable. Once you plug those into the equation above, you would get 92 dollars for the thirteen rides.
