Answer:
−12s2+11st−2t2
Step-by-step explanation:
Hope this helps!
Y=25 because 19-2+8 equals 25 so y = 25
Answer:
-1/240 (Might be wrong though)
Step-by-step explanation:
The first thing we need to do is multiply 1/15 and 1/16 because product means the answer to a multiplication equation.
1/15 times 1/16 = (1*1)/(15*16) = 1/240
Now that we know the product 1/240, we just have to find the opposite, which is -1/240 because you just add a negative sign in opposites( even in negative numbers)
Answer:
A yes, B no
Step-by-step explanation:
The triangle inequality states that the sum of any 2 sides of the triangle must be greater than the third side.
A Given 21, 18, 17 , then
21 + 18 = 39 > 17
21 + 17 = 38 > 18
18 + 17 = 35 > 21
Thus the triangle could exist
B Given 3, 12, 8 , then
3 + 12 = 9 > 8
3 + 8 = 11 < 12 ← fails the test
Thus the triangle does not exist
Answer:
80
Step-by-step explanation:
The median is the middle value of the data arranged in ascending order. If there is no exact middle then the median is the average of the 2 values either side of the middle
Arrange the data in ascending order ( smallest to largest )
32, 77, 78, 82, 85, 87
There is no value exactly in the middle, use the average
median = 
= 
= 80
