D. 9
F. 7
Step-by-step explanation:
A triangle has sides a,b and c:
And a < b+c , b < a+c and c < b+a
Here, a = 4 and b = 7
Find c?
So, 4 < 7+c , 7 < 4+c and c < 4+7=11
A. 11 False, it doesn't satisfies inequality third
B. 5 True
C. 17 False, it doesn't satisfies inequality third
D. 9 True
E. 3 Not true it doesn't satisfies second inequality
F. 7 True
Answer:
Step-by-step explanation:
5x + 5y = 20
2x - 5y = 15
7x = 35
x = 5
5 + y = 4
y = -1
(5, -1)
