Juan used the expression 16 – 9 – 12 + 22 to find his profit for days 2 and 3. he rewrote the expression as 16 + (–9) + (–12) + 22. juan can use the associative and commutative properties to rewrite the expression again. explain why he had to use the additive inverse before he could use these properties.

Associative property and commutative property true for addition, not true for subtraction.

Step-by-step explanation:

Associative property and commutative property true for addition.

i) a + (b + c) = (a + b) + c  ---> Associative property of addition

ii) a + b = b + a --> commutative property of addition.

These properties not true for subtraction.

That's the reason Juan used additive inverse before applying these property.

Hope this will helpful.

Thank you.

the dimensions are:

step-by-step explanation:

we want to find the dimensions of a rectangular box with volume of

we factor to obtain;

we rewrite the rightmost factor to obtain;

recall that:

we apply difference of two squares formula to obtain;

hence the dimensions are
