Re-written, I believe the equation is:
(W+23)+5=W+(23+5)
With this, the parenthesis have nothing multiplying into it, so we can drop the parenthesis to get:
W+23+5=W+23+5
Which is the same thing.
So I'd assume it is the Associative property, because you are combining the like terms of 23 and 5.
Hope this helps!
Let's factorise it :
![\: {\qquad \dashrightarrow \sf ( {x}^{3} - 5)(x + 3) }](https://tex.z-dn.net/?f=%5C%3A%20%7B%5Cqquad%20%20%5Cdashrightarrow%20%5Csf%20%20%20%28%20%7Bx%7D%5E%7B3%7D%20%20%20-%20%205%29%28x%20%2B%203%29%20%20%7D)
![\: {\qquad \dashrightarrow \sf {x}^{3} (x + 3) + [-5(x + 3)] }](https://tex.z-dn.net/?f=%5C%3A%20%7B%5Cqquad%20%20%5Cdashrightarrow%20%5Csf%20%20%20%20%7Bx%7D%5E%7B3%7D%20%28x%20%2B%203%29%20%2B%20%5B-5%28x%20%2B%203%29%5D%20%20%7D)
Using Distributive property we get :
![\: {\qquad \dashrightarrow \sf {x}^{3} + {3x}^{3} + ( - 5x - 15) }](https://tex.z-dn.net/?f=%5C%3A%20%7B%5Cqquad%20%20%5Cdashrightarrow%20%5Csf%20%20%20%20%7Bx%7D%5E%7B3%7D%20%2B%20%20%7B3x%7D%5E%7B3%7D%20%20%20%2B%20%28%20-%205x%20-%2015%29%20%20%7D)
![\: {\qquad \dashrightarrow \sf {x}^{3} + {3x}^{3} - 5x - 15 }](https://tex.z-dn.net/?f=%5C%3A%20%7B%5Cqquad%20%20%5Cdashrightarrow%20%5Csf%20%20%20%20%7Bx%7D%5E%7B3%7D%20%2B%20%20%7B3x%7D%5E%7B3%7D%20%20%20-%205x%20-%2015%20%7D)
![\: {\qquad \dashrightarrow \sf 4{x}^{3} - 5x - 15 }](https://tex.z-dn.net/?f=%5C%3A%20%7B%5Cqquad%20%20%5Cdashrightarrow%20%5Csf%20%20%20%204%7Bx%7D%5E%7B3%7D%20%20-%205x%20-%2015%20%7D)
⠀
Therefore,
![\: {\qquad \dashrightarrow \sf ( {x}^{3} - 5)(x + 3) =4{x}^{3} - 5x - 15}](https://tex.z-dn.net/?f=%5C%3A%20%7B%5Cqquad%20%20%5Cdashrightarrow%20%5Csf%20%20%20%28%20%7Bx%7D%5E%7B3%7D%20%20%20-%20%205%29%28x%20%2B%203%29%20%20%20%3D4%7Bx%7D%5E%7B3%7D%20%20-%205x%20-%2015%7D)
Answer:
you can do 3 x 6 + 8 - 2
Step-by-step explanation:
3 × 6= 18
+8= 26
-2= 24
hope this Helps :)
80 because 160 divided by 2 is 80 so 2 x 80
Answer:
1) +80
2) -1520
Step-by-step explanation:
Positive Signed numbers are used in real world situations to indicate the increase. Examples include; increase in weight, deposit of money into an account, increase in income, profit, height above sea level, etc. They are all represented by positive signed numbers.
Whereas, negative signed numbers show decrease. Examples include; loss of weight, withdrawal of money from an account, loans, liabilities, losses, temperature below zero degrees, height below sea level.
1) We are told that Reuben received 80 dollars. Thus, it means he received an increase in the amount of money he already had. Thus, the signed number will be +80.
2) We are told that A car corporation produced 1520 fewer cars this month than last.
Thus, the signed number will be negative since there is a decrease in number of cars.
Thus, signed number = -1520
