Hi, again, Can you help me understand this?
1 Identify one way to rewrite the expression using the distributive property. 8 * 19=
2 Identify one way to rewrite the expression using the distributive property. 2(9+3)
3 Simplify using the Distributive property 7*48
4 Simplify using the Distributive property 9*81
Please help me understand this, thank you!!
B
D
A
C
1. (8 x 20) - (8 x 1)
2. (2 x 9) + (2 x 3)
3. (7 x 50) - (7 x 2) = 350 - 14 = 336
4.(9 x 80) + (9 x 1) = 729
Now idk if these are exactly in order, but I got 100%.
I am a Retired Electronics Design/Reliability Engineer. I taught electronics at Lawrence Tech for 4 years. I am the inventor of the Tire Pressure Monitor which is used in all road vehicles manufactured after Fall of 2007.
I have a total of 3 patents.
Well, I don't have one, I just need help understanding this.
8*19 = 8 * (20 - 1) = 8*20 - 8*1
= 160 - 8
= 152
or if you want to get fancy
8 * 19 = (10-2)(20-1) = 200 - 10 - 40 + 2
= 200 - 50 + 2
= 152
:)
9*81
oh fun
(10-1)(80+1) = 800 +10 -80 - 1
= 730 - 1 = 729
thanks unknown 100%
thanks Graice
1. 8 x 19
Answer: (8 x 20) - ( 8 x 1)
2. 2(9 + 3)
Answer: (2 x 9) + (2 x 3)
3. 7 x 48
Answer: (7 x 50) - (7 x 2) = 350 - 14 = 336
4. 9 x 81
Answer: (9 x 80) + (9 x 1) = 729
I took the assessment and got 100%, these are the right answers.
Hope this helps with your grades guys.
I thank you, Star, for thanking your time for this, but that really doesn't help, But however Who Know( my teachers) I can use that info.
WAIT What's "inverse"
Like? NM about the help................
7*48 = 7(50-2) = 350 -14 = 336
You are welcome.
Thank you Henry2.
whats the answer???????????????????????????????????/
THANK YOU SO MUCH @UNKNOWN I GOT A 100 PERCENT THANK YOU !!!!!!!!!!!!!!! 😁👍😎😁(●'◡'●)╰(*°▽°*)╯(^///^)
UNKNOWN, you'd better be right!!!
OMG!,OMG!!!. I got a 100%!!! Anyone who needs the answers LOOK AT UNKNOWN's response.
Using the distributive property, an expression equivalent to 48 + 30 is
Thank you:) I got %100.
unknown is correct 100%
thx ^_^
flip backwards
Like esrevni? Or ,.......WHAT?
flip
I still don't understand can you re-spell it ?

Thank you Mr. Damon
1. 8*19 = 8*(11+8).
2. 2(9+3) = 2 * 12.
Note: The quantity in parenthesis is replaced by its' equal.
@Henry2

to unknow
thx Gracie Muskelia is correct i got 4/4 (100%)
Gracie is correct as is January 25 2023 for connexus 6th grade
2(9+3) = 18 + 6 = 24
or
2(9+3) = 2(10 + 2) = 20 + 4 = 24
or
2(12) = 24
whatever :)
I got 2/4
communitive
identity
inverse
associative
what's your answer
Star --
Do you mean

Please do not post wrong answers! Please watch your spelling?
