Matt is showing his work in simplifying (6.2 − 1.6) − 4.4 + 7.8. identify any error in his work or reasoning. step 1: (6.2 − 1.6) − 4.4 + 7.8step 2: 6.2 + (− 1.6 − 4.4) + 7.8 (commutative property)step 3: 6.2 − 6 + 7.8step 4: −14 − 6 = 8 (commutative property)step 5: 14 − 6 = 8 he wrote commutative instead of distributive in step 4. he wrote commutative instead of distributive in step 2. he wrote commutative instead of associative in step 4. he wrote commutative instead of associative in step 2.

Formatting first:

Step 1: (6.2 − 1.6) − 4.4 + 7.8

Step 2: 6.2 + (− 1.6 − 4.4) + 7.8 (commutative property)

Step 3: 6.2 − 6 + 7.8

Step 4: −14 − 6 = 8 (commutative property)

Step 5: 14 − 6 = 8

Step 2 is the associative property (a+b)+c=a+(b+c)

Step 4 is just wrong with -14 instead of 14; seems corrected in step 5.

He wrote commutative instead of associative in Step 2.

definition: a circle is the  set of all points in a plane that are equidistant  from a given  point  called the center of the circle. we use the symbol ⊙ to represent a circle. the a line segment from the center of the circle to  any point  on the circle is a radius of the circle.

i googled it and this is what i got i don't know how it is. sorry.
