<h3>
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.
Answer:
y² + bs²y - 6b²s⁴
General Formulas and Concepts:
- Expand by FOIL (First Outside Inside Last)
- Exponent Power Rule:
Step-by-step explanation:
<u>Step 1: Define expression</u>
(y - 2bs²)(y + 3bs²)
<u>Step 2: FOIL</u>
- First: y · y = y²
- Outside: y · 3bs² = 3bs²y
- Inside: -2bs² · y = -2bs²y
- Last: -2bs² · 3bs² = -6b²s⁴
<u>Step 3: Simplify</u>
- Combine: y² + 3bs²y - 2bs²y - 6b²s⁴
- Combine like terms: y² + bs²y - 6b²s⁴
Answer:
C and D is correct
Step-by-step explanation:
C: Debit is negative, and if you add 27 to -14, you get 13 which is Maria's account.
D: Its the same thing but opposite. 13 minus 27 is -14.

Answer:
Step-by-step explanation:
-12 = 4(-6 + f)
-12 = (-6 * 4 + f * 4)
-12 = (-24 + 4f)
-12 = -24 + 4f
Solving for variable 'f'.
Move all terms containing f to the left, all other terms to the right.
Add '-4f' to each side of the equation.
-12 + -4f = -24 + 4f + -4f
Combine like terms: 4f + -4f = 0
-12 + -4f = -24 + 0
-12 + -4f = -24
Add '12' to each side of the equation.
-12 + 12 + -4f = -24 + 12
Combine like terms: -12 + 12 = 0
0 + -4f = -24 + 12
-4f = -24 + 12
Combine like terms: -24 + 12 = -12
-4f = -12
Divide each side by '-4'.
f = 3
Simplifying
f = 3
