Consider the following table.
15) 5/8
16)21.16 meters
17)C
-9 - 3 / 1 - (-7)
This can be simplified to -12/8 or -3/2.
4 - 3 - 6x³ - 2y³ + 3x³ + 5 + 2y³
4 - 3 + 5 - 6x³ + 3x³ - 2y³ + 2y³
6 - 9x³
Step-by-step explanation:Step-by-step explanation:
For Sienna to be able to take the square root of both sides while solving a quadratic equation, she must have an expression with square on at least, the side that contains the variable she is trying to determine. Equation of the form:
(x + a) ² = b
'a' and 'b' could be any number, -1, 0, 1/3, -5/6, anything really.
So, she can take square roots of both sides then, like this
√(x + a)² = √b
x + a = ±√b
x = -a ± √b
Square roots always cancel out squares, and the '±' is because a square is satisfies by both + and -, 3² = 9, and (-3)² = 9.
It is the nature of the problem being solved that determines if we take just one or both of these answers.
