Sherry thinks 7, 7 and 12 are side lengths of a right triangle. Do you agree or disagree? Justify your reasoning. PLEASE NOW!!!!
AleksAgata [21]

Answer:

disagree

Step-by-step explanation:

If the triangle is right, then the square of the longest side must equal the sum of the squares on the other 2 sides.

longest side = 12 ⇒ 12² = 144

7² + 7² = 49 + 49 = 98

Since 144 ≠ 98 then triangle is not right

6.The expressions 5 + 2(x –7) and 5 +2x –14are equivalent by the
satela [25.4K]

Answer:

6) Option B) distributive property  is correct

Therefore 5+2(x-7)=5+2x-14 are equivalent by using distributive property

7) Option B) distributive property  is correct

Therefore  x+3(7-x)=x+21-3x are equivalent by using distributive property

Step-by-step explanation:

6) Given that the expressions 5+2(x-7) and 5+2x-14 are equivalent

To verify that the given expressions are equivalent by which property :

5+2(x-7)

=5+2(x)+2(-7) ( by using the distributive property a(x+y)=ax+ay )

=5+2x-14

Therefore 5+2(x-7)=5+2x-14 are equivalent by using distributive property

Therefore option B) distributive property  is correct

7) Given that the expressions x+3(7-x) and x+21-3x are equivalent

To verify that the given expressions are equivalent by which property :

x+3(7-x)

=x+3(7)+3(-x) ( by using the distributive property a(x+y)=ax+ay )

=x+21-3x

Therefore  x+3(7-x)=x+21-3x are equivalent by using distributive property

Therefore option B) distributive property  is correct
