For this case we have the following expression:
x ^ 2 + 15x + 56
We can factor this expression to find the possible dimensions of the rectangle.
Factoring we have:
(x + 7) (x + 8)
Answer:
the possible dimensions are:
(x + 7) * (x + 8)
Answer:
Test A: 40 words per minute
Test B: 54 words per minute
Test C: 44 words per minute
<em><u>Test B has the highest unit rate</u></em>
Step-by-step explanation:
Test A divide 30 by 
(30/0.75=40)
Test B divide 78 by 
(78/1.5=52)
Test C divide 99 by 
(99/2.25=44)
<u>Hope this helps :-)</u>

Answer:
The distributive property helps in making difficult problems simpler. You can use the distributive property of multiplication to rewrite expression by distributing or breaking down a factor as a sum or difference of two numbers.
Here, for instance, calculating 8 × 27 can made easier by breaking down 27 as 20 + 7 or 30 − 3.
Step-by-step explanation:
To start, note that the roots of a function have to do with how many times the function passes through the x-axis.
When you look at the graph above, notice that it passes through the x-axis 3 times, at the points (-6,0), (-4,0), and (3,0).
Knowing this, you can conclude that your answer would be choice B.)3
