The last one is the correct answer!! nothing that is dilated can be congruent to another triangle.
Okay, so a half-life means that every so and so (which in this case is 4 hours), what we have is now equal to half of that (although it does do this more gradually).
The answer to this would be 50(0.85)x
42.052
place value and digits:
4 = tens
2 = ones
0 = tenths
5 = hundredths
2 = thousandths
5 is in the hundredths place. To find if you round up or down, look at the digit to the right (thousandths in this case). It is a 2, which is less than 5, so you round down.
42.052 rounded to the nearest hundredth is 42.05
hope this helps
Answer:
positive
Step-by-step explanation:
Answer:
( 2x + 1 ) (x + 1 )
Step-by-step explanation:
2x² + 7x + 3
m+n = b = <u>7</u>
m · n = a · c = 2 · 3 = <u>6</u>
m = 6
n = 1 because 6 + 1 = <u>7</u> and 6 · 1 = <u>6</u>
2x² + <u>1</u>x + <u>6</u>x + 3
x ( 2x + 1 ) + 3 ( x + 1 )
( 2x + 1 ) (x + 1 )
