The volleyball team and the wrestling team at Stamford High School are having a joint car wash today,
Sedbober [7]

Answer:

Money raised by each team = 94 + 11 = <em>$105</em>

Number of cars washed = <em>11</em>

Step-by-step explanation:

Money already present with volleyball team = $50

Money raised by washing each car by volleyball team = $5

Let the number of cars washed = x

Money raised by washing cars = $5x

Money already present with volleyball team = $94

Money raised by washing each car by volleyball team = $1

Money raised by washing cars = $1x = $x

Given that, both the teams have raised same amount of money:

50+5x=94+x\\\Rightarrow 44=4x\\\Rightarrow x=11

Money raised by each team = 94 + 11 = <em>$105</em>

Number of cars washed = <em>11</em>

Which function models the area of a rectangle with side lengths of 2x - 4 units and x + 1 units?
aalyn [17]

Answer:

Area of rectangle, f(x)=2x^2-2x-4.

Step-by-step explanation:

We are given with side lengths of a rectangle are (2x-4) units and (x+1) units. It is required to find the area of rectangle.

The area of a rectangle is equal to the product of its length and breadth. It is given by :

A=L\times B

Let us consider, L = (2x-4) units and B = (x+1) units

Plugging the side lengths in above formula:

A=(2x-4)\times (x+1)

A=2x^2+2x-4x-4\\\\A=2x^2-2x-4

So, the function that models the area of a rectangle is f(x)=2x^2-2x-4.
