Answer: D.
Step-by-step explanation: you find the ratio of the other lengths, then apply that ratio to the length of DC. Pls mark as brainliest?
A.. 9.5*3.6=34.2 then 34.2/5.7= 6 so 6 is your answer
B. 16.2*5.7= 92.34 then 92.34/3.6= 25.65
If I’m getting this right the equation is: 0.00045 - 2.5 x 10 - 5? The dot in between 2.5 and 10 indicates a multiplication sign
So...
0.00045 - (2.5 x 10) - 5
0.00045 - 25 - 5
= -29.9999 -> -30
