I am help my 12 year old daughter could someone tell me if these are right.
Simplify the expression(CLT) 4+ (7p+ 8a-9+) =4+14p+16a-18t
4 +14p + 16a-18t
2x-5(2x-7y+3)+(-8)
2x-10x +35y -15-8
35y- 8x-23
7-12(2h-3w)+(-8)
7-24h+36w-8
36w-24h-1
I have being out school for a while over 40 year so could someone tell me if this r right
I don't understand your question.
What is CLT ?
you said: 4+ (7p+ 8a-9+) =4+14p+16a-18t ,
which is incorrect.
What is 9+ ? is that supposed to be 9t ?
4 + (7p + 8a - 9t)
= 4 + 7p + 8a - 9t
that is all you can do with it, why did you multiply the terms in the bracket by 2 in your answer?
2x-5(2x-7y+3)+(-8)
= 2x-10x +35y -15-8
= 35y- 8x-23 <----- correct
7-12(2h-3w)+(-8)
= 7-24h+36w-8
= 36w-24h-1 <----- correct
took me a while to figure out there were 2 questions after that first one.
You should number them and use equal signs.
