A. First move all to the left side of the equation(Normal form)
x^3 - 49x= 0
B. Factor out an x, which is the GCF (Factored form)
x(x^2 - 49) = 0
C. Find solutions by making each x piece equal to 0. The first part is just x=0 and the second part is just factoring the difference of squares and then solving.
x=0, x^2 - 49 =0
x=0, x + 7 = 0, x - 7 = 0
Therefore, the answers for Part C are:
x = 0, x = -7, x = 7
Answer:
False
Step-by-step explanation:
There are no real numbers that are considered rational or irrational numbers. The definition of a real number is that it's a combination of both rational and irrational numbers.
This is showing a corresponding pair of angles. So x would equal 34 degrees. (If it was a linear pair, it would be 180-34)
You have 30 more cds than your friend
So it would be your friends CDs + 11 = your CDs, which is 30
n + 11 = 30
