So for this, factor x^3 + x^2 and x + 1 separately. Make sure that they have the same quantity on the inside: 
Now you can rewrite the expression as: 
, which is your final answer.

77 centimeters
Step-by-step explanation:
You have to divide 4389 cm bye 57 cm, and the answer is 77 centimeters.
Answer:
Below in bold.
Step-by-step explanation:
f(n) = |-2n| - 6
The vertical lines about the -2n mean the 'absolute value' of the expression So if -2n is negative the absolute value is positive.
n = 19 , f(n) = |-2*19| - 6 = |-38| - 6
= 38 - 6 = 32.
In the same way:
n = 20, f(n) |-40| - 6 = 40 - 6
= 34.
n = 21, f(n) = 36
n = 22, f(n) = 38.
Answer:
x = 13
Step-by-step explanation:
Since this is a right triangle, we can use the Pythagorean theorem
a^2 + b^2 = c^2 where a and b are the legs and c is the hypotenuse
5^2 + 12^2 = x^2
25+144 = x^2
169 = x^2
Taking the square root of each side
sqrt(169) = sqrt(x^2)
13 =x
