only a dilation would make the figures not congruent/similar
The above is a simple math problem and the answer to x which is the unknown is -6.5 approximately.
<h3>What is the calculation for the above answer?</h3>
First, lets rewrite the word problem:
-1.96321 and - √(x) = 5
Note that "and" is also multiplication in math.
Hence,
-1.96321 * - √(x) = 5
- √(x) = 5/-1.96321
-x = (5/-1.96321)²
- x = 6.48644131993
x = - 6.48644131993
x 
-6.5

The activation energy is the amount of energy required to initiate a certain reaction. The activation energy may considered as an "energy barrier" that has to be overcome in order for a reaction to begin. If a reaction has a lower activation energy, then it will occur more easily and at a faster rate than a reaction with a higher activation energy. Therefore, the reason that reaction 1 is faster than reaction 2 is because it has a lower activation energy than reaction 2.
45 degrees because vertical angles are congruent
Answer: 18x+16 cm
Step-by-step explanation:
Combine the like terms. 9x+9x = 18x and 8+8=16
