The formula for the area of a rectangle is
length × width.
the length =width + 5
W + 5
width(W) =9

let the area = A
therefore the function is,
(W + 5) + 9 =area

Rectangle with area of 10 and length of 2 1/2. Whats the width?
Stels [109]
Hello!

We have been given enough information to solve this question!
We know that the length of the rectangle is 2.5, and we also know how to find the area:

A = l × w

But we don't need the area, we need to find the width of the rectangle! You see, we had to multiply the length by the width to find the area.

Now, to find the width, we must flip the problem around and use the opposite of multiplication, which is division.

W = a ÷ l

W = 10 ÷ 2.5

W = 4

Therefore, the width of the rectangle is 4.

If x metres of string are cut from a piece y metres long how much is left?
Karolina [17]

Answer: The new length is: (y - x) metres.

Step-by-step explanation:

If we have a piece of string that is y metres long, and we cut x metres of strings from it, then the new length of the string will be equal to the difference between the initial length and the amount that we cut off.

So the initial length is y metres.

We cut x metres.

The new length is: (y - x) metres.

What are the slope between (-5,-2) and (8,13)​
Cerrena [4.2K]

Answer:

The slope:

m = \frac{15}{13}

Step-by-step explanation:

-To determine the slope of the following points shown, you need this formula:

m = \frac{y_{2} - y{1}}{x_{2} - x_{1}}

(m represents the slope, (x_{1}, y_{1}) represents the first coordinate and (x_{2},y_{2}) represents the second coordinate)

-Apply the following points to the formula:

m = \frac{13 + 2}{8 + 5}

Then, solve:

m = \frac{13 + 2}{8 + 5}

m = \frac{15}{13}

So, the slope is \frac{15}{13}.
