The answer is 977 seconds squared
Answer:
47
Step-by-step explanation:
The diagonals of a parallelogram bisect in their middle point, so :
2u + 9 = 5u - 48
3u = 57
u = 19
EI = 5* 19 - 48 = 47
-3x+5y=30
+3x+5y=30
5y=3x+30
divide 5 by everything
answer: y=3/5x+6
This is ur required result in attachment
7
5 times 7
equals 35
then you add 15
and get 50
