I believe it is commutative property cause the numbers didn't change instead they just switched places in the equation.
This is the answer in expanded form: 100,000 + 10,000 + 4,000 + 6<span />
B. $30
to find out how much $ she earned per day, all you have to do is divide $2,100 by 70, which is $30.
i hope this helps!!
Answer:
Step-by-step explanation:
Begin the solution by squaring both sides of the given equation. We get:
(3x - 4)^2 = 2x^2 - 2x + 2, or:
9x^2 - 24x + 16 = 2x ^2 - 2x + 2
Combining like terms results in:
7x^2 - 22x + 14 = 0
and the coefficients are a = 7, b = -22, c = 14, so that the discriminant of the quadratic formula, b^2 - 4ac becomes (-22)^2 - 4(7)(14) = 92
According to the quadratic formula, the solutions are
-b ± √discriminant -(-22) ± √92 22 ± √92
x = ------------------------------- = ----------------------- = ------------------------
