X^2 + 8x + 7 = 0
x^2 + 7x + x + 7 = 0
x(x + 7) + 1(x + 7) = 0
(x + 7) (x + 1) = 0
x = -7 or x = -1
Answer:
When the leading coefficient is positive, the graph opens up. It means the vertex is its minimum.
When the leading coefficient is negative, the its vertex is its maximum.
- f(x) - vertex is minimum
- g(x) - vertex is maximum
1 degree is 
radians. So 14 degrees is 
rad.
Easy way to remember this: one complete revolution in a circle is 360 degrees. But it's also 
radians. So the conversion rate is
i.e. for every 
radians there are 180º.
Answer:
Similarity means that two figures are the same shape, but not necessarily the same size, color or orientation, congruent means two figures are the same in every form.
Step-by-step explanation:
In my understanding, The Property of Rigid motion holds two points:
- The relative distance between two points stays the same,
- The relative position of the points stays the same
This includes, translations, reflections, and rotation but not to dilutions since it breaks these rules. The relative distance between points gets smaller after dilution.
