If the length of the rectangle is x, then we know the width is x + 1.
The area of a rectangle is length · width, so we can substitute as x · (x + 1)
Now, we now x · (x + 1) = 42
Expand
x² + x = 42
Solve
x² + x - 42 = 0
(x + 7)(x - 6) = 0
So, x = 6
That means the length is 6 meters and the width is 7 meters.
Answer:
<em>Spaghetti and Pizza are preferred almost equally.</em>
Step-by-step explanation:
Daniel surveyed a random sample of 100 students from his middle school to learn more about what type of school lunches are preferred based on his observation the table of the following is given as:
<u> Hamburgers </u> <u>Spaghetti </u> <u> Pizza</u>
<u>Sample 1:</u> 13 43 44
-----------------------------------------------------------------------
<u>Sample 2:</u> 20 41 39
-------------------------------------------------------------------------
<u> Total:</u> 33 84 83
By looking at the table we see that the total number of spaghetti and Pizza chosen are almost equal as:
Total number of Spaghetti preferred=84.
and Total number of Pizza preferred=83.
