Expand the equation by multiplying it with itself: (x-3)*(x-3)
x^2 - 3x - 3x + 9 = 5
x^2 - 6x + 9 = 5
x^2 -6x +4 = 0
Since this is not part of the choices, try a different approach. Take the square root of both sides:
x - 3 = square root of 5
x - 3 = +/- 2.24
I guess this is the middle term which is incomplete. The first and last choices are not equivalent to the given equation.
Answer:
He receives $476 in comission.
Step-by-step explanation:
This question can be solved using a rule of three.
$6,800 is 100% = 1. x, which is his commision, is 7% = 0.07. Then
6800 - 1
x - 0.07
x = 6800*0.07
x = 476
He receives $476 in comission.
The answer is c hope this helps
Answer: -54
Step-by-step explanation:
The question is the first term of a geometric sequence is −2 and the common ratio is 3. The formula for finding the nth term of a geometric sequence is: ar^n-1
where,
a = first term = -2
r = common ratio = 3
n = number of terms = 4
The solution has been attached. The answer is -54
Any number above 1 gets greater, below 1 smaller (when above 0), while 1 itself remains the same. Negative numbers are more unpredictable.
