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
Answer:
40 m
3(a-b) and 3a-3b. Equivalent
2a(2+b) and 4ab. Not equivalent
hope this helps:)
recall that a/b to decimal is just a ÷ b, so 2/9 is just 2 ÷ 9.
