Answer:
7
Step-by-step explanation:
When you match the form
... ax² + bx + c = 0
to the equation
... 3x² + 5x + 7 = 0
it is reasonable to conclude that ...
... a = 3, b = 5, c = 7.
_____
The question presumes you are familiar with the form
... ax² +bx +c = 0
which is often used as the representation of a general quadratic equation. This lets us use a, b, and c instead of specific numbers, to talk about ways of factoring, graphing, or solving equations like this.
18.5-0.5= 18
18/3= 6
So r=6
Answer:
A. Symmetric Property
Step-by-step explanation:
The Symmetric Propertry states that if x = y, then y = x.
Since XY = WX, and WX = XY, its the Symmetric Property.
