Answer: 20.5
Form your equation. The formula for perimeter is (2l)(2w) or l + l + w + w, where l = length and w = width.
(l - 5) + (l - 5) + (l) + (l) = 72
Simplify and solve your equation.
4l - 10 = 72
4l = 82
l = 20.5
Since l = length, length = 20.5 and width = 15.5
You can check your work, too:
20.5 + 20.5 + 15.5 + 15.5 = 72
Answer: x = -16
Step-by-step explanation:
3x - 11 = -x - 75 then solve. see photo attached for work.
Answer:
C. To control both unintentional research bias and participant prior beliefs
Step-by-step explanation:
Double blinding is a type of study where neither the participants nor the researchers know the treatment or intervention that the participants receive until the whole study/research is completed. This is very important because it means that the results gotten from the study have a very slim chance of being biased.
Thus,the correct answer is option C as it includes both the researcher and the participants
B is the answer as when you draw angle bisector you draw arcs that intersect at the bisector
Nine plus a unknown number equals unknown.
