The answer to your problem is just through simple calculation.
Answer: -507.428571
<span>25a^2 - 100
= 25(a^2 - 4)
GCF = 25

Subtract P from both sides and be left with -4 = -9, which means no solutions.
Answer:
The angle: 
The supplement: 
Step-by-step explanation:
By definition, if the sum of two angles is 180 degrees, then this angles are called "Supplementary Angles".
Let be:
the angle (in degrees) and 
its suppplement (in degrees).
Therefore, you can write the following equation in order to find the angle and its supplement:
Now, you must solve for "x". Then:
Then:
Answer:
r = 5mm
Step-by-step explanation:
When two shapes are similar, They are the same shape but with 1 or more basic transformations(dilations, reflections, rotations, and translations.). All sides on the new shape (green) are similar to the original shape (blue), meaning they were all dilated by the same scale factor.
First, we need to find our scale factor. To find our scale factor, take 10 and divide it by 4 (These sides are similar and we have established values so we can be sure our scale factor is correct by using these.).
10/4 = 2.5
So, our scale factor is 2.5.
Now, to solve for r, we need to find it's similar side (in this case it's 2 mm.).
Now, simply multiply the original size by our scale factor.
2 * 2.5 = 5.
So, r = 5 mm (Don't forget units, teachers hate that.)
