Step-by-step explanation:
The scientific notation:

<em>1 ≤ a < 10</em> and <em>k -</em><em> any integer number</em>
<em />

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:
2/21
Step-by-step explanation:
17/21 -(3/7 + 2/7)
First you add
=17/21 - (5/7)
Then you want to subtract
=2/21
Answer:
(x - 4)(x - 4)
x = 4
Step-by-step explanation:
x² - 8x + 16
= (x - 4)(x - 4)
x - 4 = 0
x = 4
