8/10*8/21
= 64/210
= 32/105
Answer:
Isosceles triangle
Step-by-step explanation:
Length AB
√(4 - 2)² + (7 - 2)²
√2² + 5²
√4 + 25
√29
Length AC
6 - 2 = 4
Length BC
√(6 - 4)² + (2 - 7)²
√2² + (-5)²
√4 + 25
√29
Length AB and BC is the same.
Length AC is the longest side.
Therefore, it is an isosceles triangle.
No because you don't know how many places are in the number
ex:843 and 3257
there are 4 places in 3257 and only 3 places in 843
-6r+5
the two like terms are the ones with R. combine -4r and -2r to get -6r
