B. four million eighty-four thousand and nine hundred four thousandths
If both triangles are similar the ratio of sides will be same

B. 16.30 = 16.3
if there is a 0 in a decimal and it is the farthest right place value it is the same as if the 0 wasn't there
Answer: -1 would be -d
0 -> d
1 -> f
2 -> stays same
(if this is not the right answer I'm sorry because i learned this awhile ago
Normally, we could add exponents.
however, that only is possible when the bases are the same
recall what exponents mean
12³=12*12*12
so we cannot add exponents for 12³*11³ because that means 12*12*12*11*11*11
it would not equal 12⁶ or 11⁶
or you could refer to the rule

notice when x=x then we can add the bases
fun fact below
we can reverse a previous exponential rule like this
since

then

therefor

we can't add the exponents because the bases are not the same
