Step-by-step explanation:
Distribute parenthesis and collect like terms, noting that the second parenthesis is distributed by - 1
(4x² - 8xy +2y²) - (9x² - 4xy - 7y²)
= 4x² - 8xy + 2y² - 9x² + 4xy + 7y² ← collect like terms
= (4x² - 9x²) + (- 8xy + 4xy) + (2y² + 7y²)
= - 5x² - 4xy + 9y² → b
Answer:
15.6 in.
Step-by-step explanation:
If the volume of the box is scaled down by a factor of 1/10, that means you just have to move the decimal over to the left by one place value, making the new volume 15.6 in because behind the 156 there's an invisible decimal in case you need it.

Answer: 15+2x</h3>
=======================================
The commutative property of addition is where we can add two numbers in any order we want. Example: 2+3 = 5 and 3+2 = 5.
In general, the rule is x+y = y+x.
In our case, 2x and 15 can be added in any order. So that's why 2x+15 is the same as 15+2x.
-------
Side note: a similar rule applies for multiplication as well. This is called the commutative property of multiplication. Example: 9*3 = 27 and 3*9 = 27. So we can say x*y = y*x.
