First, find the scale factor.

8.4 / 7 = 1.2

9 / 7.5 = 1.2

7.2 / 6 = 1.2

Since both solids are different sizes, the solids aren't congruent.

The size ratio for all the sides are:

8.4:7

9:7.5

7.2:6

Since the scale factor isn't 1:1 this also proves that the solids are NOT congruent.

Since both solids are the same kind of shape and have an identical scale factor, the solids are similar.

Best of Luck!

Find the infinite sum of 10,5,2.5,1.25...

____ [38]

Notice this is a geometric progression since each number multiplied by some factor equals the next number in the sequence, in this case,

$10 \times r = 5 \Rightarrow r=0.5$

Then by applying the formula for sum to infinity of a geometric progression,
$S_\infty = \frac{a}{1-r} = \frac{10}{1-0.5} = 20$
