Answer:
2,4 and 7 do not form a triangle
Step-by-step explanation:
To form a triangle, knowing the 3 sides, then
The sum of any 2 sides must be greater than the third side
Consider 2, 4, 7
2 + 4 = 6 < 7
2 + 7 = 9 > 4
4 + 7 = 11 > 2
Since 2 + 4 < 7
Then these 3 sides would not form a triangle
Im pretty sure than this would be 43x30 and that equals 430
Answer:
1
Step-by-step explanation:
1 1/3 = 4/3
4/3 - 1/3
drop the bottom 3 since it is a common denominator
4 - 1 = 3
bring the 3 back
3/3 = 1
Answer:
2m - 20
Step-by-step explanation:
Given that:
First week minutes = m
Second week minutes = (2 * first week minutes - 20)
Second week = 2m - 20
Therefore, the expression for the number of practice minutes for the second week is :
2m - 20
