Answer:
Length is 38.7
Width is 19.3
4x length to 2x width
4+2=6
6x =116
x = 58/3
4 x 58/3 = 77.3
2 x 58/3 = 38.7
4:2
2:1
77.3/2 = 38.7
38.7/2 = 19.3
38.7 + 38.7 + 19.3 + 19.3 = 116
<span>mostly collect like terms
use associative property which is
(a+b)+c=a+(b+c)
also -a+b-c=(-a)+(b)+(-c) so you can move them around
and remember that:
you just use a general rule
x+x=2x
x^2+x^2=2x^2
3xy4xy=7xy
3x+4x^2=3x+4x^2
you
can only add like terms( like terms are terms that are same name like x
or y are differnt, and like terms have same power exg x^2 and x^3 and
x^1/2 and such
I will oly put the naswers because I don't have much time
first one: 2a+3b+2c
second one: remember that -(-6c)=+6c so the answer is c-10a-2b
third one: -a-8b-5c

I think it’s option 3, I’m not sure
A. 25/40 , 36/40, 49/ 40.
you are adding by odd numbers example 1+3=4. 4+5=9 .9+7=16. 16+9=25 and so on.
b. 47/101, 76/101, 123/101
you are adding by the answers
example. 3+1=4. 4+3=7. 7+4=11. 11+7= 18. 18+11= 29. 29+18=47. 47+29=76. 76+47=124.
