Option (b) is the correct answer as the expression
.
Let's break down each expression to determine their equivalence:
a.
![\(2\left((2)/(5)x + 2\right) = 2\left((2)/(5)x\right) + 1\)](https://img.qammunity.org/2023/formulas/sat/high-school/2yqv99xrp5wwsg676kvy1c9s55qgwfab96.png)
Expanding the left side:
![\(2 * (2)/(5)x + 2 * 2 = (4)/(5)x + 4\)](https://img.qammunity.org/2023/formulas/sat/high-school/p8wzxo1g4nlnhsq2d94yearxf9rmqofdmq.png)
The right side does not match, so option (a) is not equivalent.
b.
![\(2\left((2)/(5)x + 2\right) = (4)/(5)x + 4\)](https://img.qammunity.org/2023/formulas/sat/high-school/pimyed97ursbuhpy9baaxu2idm16vwclru.png)
This matches the expanded left side of option (b), so option (b) is equivalent.
c.
![\(2\left((2)/(5)x + 4\right) = (4)/(5)x + 8\)](https://img.qammunity.org/2023/formulas/sat/high-school/lqvtay959d3rpaogecn80kckwk3r9hxjug.png)
This does not match the expanded left side of option (c), so option (c) is not equivalent.
d.
![\(2\left((2)/(5)x + 4\right) = 2\left((2)/(5)x\right) + 8\)](https://img.qammunity.org/2023/formulas/sat/high-school/2u6iv3qf6hqzjukcogsprhyijl7p1ihwau.png)
Expanding the left side:
![\(2 * (2)/(5)x + 2 * 4 = (4)/(5)x + 8\)](https://img.qammunity.org/2023/formulas/sat/high-school/sh7uysyypctetgd8bb1dhgzuk5r8z8ga7j.png)
This matches the expanded left side of option (d), so option (d) is equivalent.
In summary, the equivalent pair is option (b).
The question probable maybe:
Which pair shows equivalent expressions?
a.
![2(( 2/5 x)+2)=2 (2/5 x)+1](https://img.qammunity.org/2023/formulas/sat/high-school/3pdlj72bgki8pelyw5lqamb6rg2s6vaitr.png)
b.
![2( (2/5 x)+2)= (4/5 x)+4](https://img.qammunity.org/2023/formulas/sat/high-school/6s3vmc879gc3b5oo6geqvvhmnell4827d6.png)
c.
![2( (2/5 x)+4)= (4/5 x)+2](https://img.qammunity.org/2023/formulas/sat/high-school/tfwjsiudji0hvvpkgo7tcg37linls1pbaz.png)
d.
![2( (2/5 x)+4)=2( 2/5 x)+8](https://img.qammunity.org/2023/formulas/sat/high-school/thrbgh078rjiptqpo9k8sio1ynhaoq1cwf.png)
