.(1 point)
Responses
2abcd
2 a b c d
a+b+cd+c
a plus b minus c d plus 2 c
a+b+cd+2c
a plus b minus c d minus 2 c
a+b+cd+2
The correct answer is: a+b+cd+2c
Are the expressions 3+(4x+1)
and 4−4x
equivalent?(1 point)
Responses
Yes, they are because both expressions simplify to 4−4x
.
Yes, they are because both expressions simplify to 4 minus 4 x .
Yes, they are because both expressions simplify to 0.
Yes, they are because both expressions simplify to 0.
No, they are not because 3+(4x+1)
simplifies to x+1
, which is not equivalent to 4−4x
.
No, they are not because 3 minus left parenthesis 4 x plus 1 right parenthesis simplifies to x plus 1 , which is not equivalent to 4 minus 4 x .
No, they are not because 3+(4x+1)
simplifies to 4+4x
, which is not equivalent to 4−4x
.
No, they are not because 3+(4x+1) simplifies to 4+4x, which is not equivalent to 4−4x.
