Answer:
1. x = -7
2. x = 6/13
3. x = 7/12
Step-by-step explanation:
1. x = 21 / -3
x = -7
2. 13x = 6
x = 6 / 13
x = 6/13

Answer:60
Step-by-step explanation:
a=13 b=13 c=10
Perimeter of =a+b+c
perimeter of =13+13+10
Perimeter of =36
S=36 ➗ 2
S=18
Area=√s(s-a)(s-b)(s-c)
Area=√18(18-13)(18-13)(18-10)
Area=√18(5)(5)(8)
Area=√(3600)
Area of =60
