Answer:
1. A. similar
2. C.
3. B. all congruent figures are also similar figures.
4. B. 22.5
5. D. two hexagons
Alvin's age + Elga's age = 84
2R + R = 84
3 R = 84
3/ 3 R = 84/ 3
R = 28
Elga's age is 28
It is important to do the
calculations very carefully. Otherwise there is nothing complicated about this
problem.
Let us assume the unknown number = x
Then
40x/100 = 55
40x = 55 * 100
40x = 5500
x = 5500/40
= 550/4
= 137.5
So
55 is 40% of 137.50. I hope the procedure is clear to you and in future
you can solve such problems on your own without requiring any help from
outside.This is the simplest way of solving such
problems.

Step-by-step explanation:
Hello!
We can use the factored form of a Quadratic to find an equation with 8 and -8 as our solution.
<h3>
Factored Form: 
</h3>
The value in each parenthesis should be 0. So 8 and -8 can be flipped and used for h and k.
This will give roots 8 and -8 for x.
A possible equation is
