The equation that does not justify the similarities of both triangles is:
Similar triangles may or may not have congruent sides.
The triangles are given as:
- Triangle PQR
- Triangle STR
The above means that, the following sides are similar
- Line segments PQ and ST
- Line segments QR and TR
- Line segments PR and SR
So, the equation that does not justify the similarities of both triangles is:

The answer is B) The initial number of bacteria is 57, and the growth rate is 31% per hour.
The expression shown is an <em>exponential expression</em>. An exponential expression usually takes the form , as this one does. A represents the <em>initial value</em>, in this case-the initial number of bacteria. B represents the <em>growth rate</em>. When it is an increasing growth rate, it will begin with 1, because it will have everything it had before, plus the percent increase, the decimal portion. In this case, a=57, and b=0.31.
Hope this makes sense!
