Let w = width
then
5w-3 = length
w(5w-3) = 14
5w^2-3w = 14
5w^2-3w-14=0
(5w+7)(w-2) = 0
w = {-7/5, 2}
throw out the negative solution leaving
w = 2 centimeters
length:
5w-3 =5(2)-3 =10-3 = 7 centimeters
0.4 is rational.
Any irrational added to a rational is irrational.
Therefore we only need to add ANY irrational to 0.4 to produce an irrational number.
Examples of irrational numbers are: pi, e, sqrt(2), sin(pi/3), tan30 degrees, etc.
Answer:
What are you asking? Whats the problem?
Answer:
-4x^3+ 7x^2 + 5x-8
Step-by-step explanation:
First, open the parentheses (make sure you distribute the '-':
6x - 3x - 4 = x - 40
3x - 4 = x - 40
2x = -36
x = -18
The solution set is {-18}
