Equations A (5x+5) and D (5x + 3) are equivalent to 3x+4+2x−1, while B (3+5x) and C (8x) are not.
The expression 3x+4+2x−1 can be simplified by combining like terms, resulting in 5x+3. Therefore, the equations that are equivalent to 3x+4+2x−1 are A (5x+5) and D (5x + 3).
Expression A (5x+5) can be simplified by combining the constant terms to 5x+3, which matches the simplified form of 3x+4+2x−1. Expression D (5x + 3) directly matches the simplified form, confirming its equivalence.
On the other hand, expressions B (3+5x) and C (8x) are not equivalent. Expression B can be simplified to 5x+3 by rearranging terms, but it does not match the original expression. Expression C (8x) is a different expression altogether and does not represent the given expression.
Expressions A and D are equivalent to 3x+4+2x−1, while expressions B and C are not equivalent.
The question probable may be:
Select the equations that are equivalent to ( 3x + 4 + 2x - 1 ):
A. 5x+5
B. 3+5x
C. 8x
D. 5x + 3
