how are sas and sss used to show that two triangles are congruent?
sas = 2 equal sides and 1 equal angle (congruent)
sss = 3 equal sides (congruent)
20 is one possible answer
24 is another possible answer the question is ambiguous
first put what you have in order. the median is the central number.
12 18 22 26 30
the median for this case is not listed in your answers. 22 is not there.
so we have to give some thought to what the sixth number was. unfortunately that leads to two possible answers
if the missing number is less than 12, the the median will be between 18 and 22. say the missing number is 10
10 12 18 22 26 30
(18 + 22)/2 = 20 would be the answer.
however if the missing number was greater than 26 (say it was 32) then the numbers would be
12 18 22 26 30 32 the average between the 3rd and 4th numbers.
(22 + 26)/2 = 48/2 = 24
both answers are possible and are listed. there is no single answer.
we are given the following expression and we are to multiply it:
2.7 × (–3) × (–1.2)
multiplying 2.7 and (–3) , starting from the left to get:
2.7 × (–3) = –8.1
then multiplying this product with (–1.2) to get:
–8.1 × (–1.2) = 9.72
since both of the terms were negative here so when negative is multiplied with another negative, it becomes positive.
therefore, the correct option is d. 9.72.
