Answer:

hen we put gas in our car, there is a relationship between the number of gallons of fuel that we put in the tank and the amount of money we will have to pay. In other words, the more gas we put in, the more money we’ll pay. Also, the less money we pay, the less gas we’ll put in our car. This relationship depends on the price of a gallon of gas. The price is the proportionality ratio that exists between the quantity “gallons of gas” and the quantity “money it takes to fill up.”

Factor x 2 + 29x - 30.<br> (x + 15)(x - 2)<br> (x + 1)(x - 30)<br> (x - 1)(x + 30)
Daniel [21]

Answer:

The correct answer is C) (x - 1)(x + 30)

Step-by-step explanation:

To find this, we need to find factors of the last number (-30) that add up to the middle number (29). In order to do this, list out all of the factors of -30.

-1 and 30

1 and -30

2 and -15

-2 and 15

3 and -10

-3 and 10

Since -1 and 30 satisfy both of the parameters, we put them into their own parenthesis along with x.

(x - 1)(x + 30)

the area of a rectangular decks is 680 square feet. the decks width is 17 feet. what is its perimeter ?
Ket [755]
The perimeter is 114 square feet. To solve this, first you divide 680 by 17, which equals 40. So the length is 40. The formula for perimeter is 2L+2W. This means you take the length and multiply it by 2, and do the same for the width, then add them together. So the equation would be:
2(40)+2(17)=Perimeter
80+34=Perimeter 
The final answer is 114 square feet.

If the length of a rectangular playground is represented by the expression 2x - 3, and the width is represented by 5x + 9, what
Nimfa-mama [501]

Answer:

The expression for area of rectangle in standard form is: 10x^2+3x-27

Step-by-step explanation:

The area of rectangle is given by:

Area = Length * Width

Here, in the question, we are given length and width of the rectangle

Length = 2x-3

Width = 5x+9

The area of the rectangle will be:

Area = (2x-3)(5x+9)\\= 2x(5x+9)-3(5x+9)\\= 10x^2+18x-15x-27\\= 10x^2+3x-27

Hence,

The expression for area of rectangle in standard form is: 10x^2+3x-27
