the area is 180 cm. to find the perimeter you would do 15+15+14+14 to get 54 cm. So for area you do (l×w) which is 15×14=180.
We need to find the area. So we multiply the dimensions.
3x1/2=1.5
1.5x4 1/2=6.75
Decimal was my go-to so we need to convert back to a fraction.
6.75= 6 3/4
So the answer is B.

Substitute <em>u</em> = <em>t</em> ³/2592 and d<em>u</em> = <em>t</em> ²/864 d<em>t</em>. Then

The probability that a 12 hour surgery is successful is <em>P</em> (12), so letting <em>T</em> = 12 gives

Answer:
Step-by-step explanation:
if your question is
"Choose the student who correctly used substitution to determine if 19 was a solution to the equation. 6 + m = 24. 6 + 19 = 24. 24 = 24. 19 is a solution. 6 + m = 24. 6 + 19 = 24. 25 not-equals 24. 19 is not a solution. 6 + m = 24. 6 + 24 = 24. 30 not-equals 24. 19 is not a solution. 6 + m = 24. 6 + 19 = 24. 25 = 24. 19 is a solution."
then juan is correct
