The answer is the first one
2(6x+20) +2(8x-16)=180
12x+16x+40-32=180
28x+8=180
X=180-8/28=6
I think so my calculation may be wrong )
Answer:
b. Multiplying decimals less than one is finding a part of a part.
Step-by-step explanation:
A part of a given number implies a selected part of a given number which can be expressed as a fraction of the number. Example, the half of any number is
.
The product of a part and another part can be expressed as;
x
= 
or,
x
= 
or,
x
=
= 
The three examples shows: a part x a part.
Therefore, it would be observed that multiplying decimals less than one is the same as finding a part of a part.

Step-by-step explanation:
A recursive rule allows us to find the term in a sequence from the previous term.
From the given geometric sequence find r the common ratio
r =
=
= - 4
Hence recursive rule is
= - 4
