OpenStudy (calculusxy):

@muscrat123 That's not correct

OpenStudy (calculusxy):

4 is with the parenthesis so you need to multiply: \[4(4)\]

OpenStudy (muscrat123):

oh yeah1! srry it looked like it was 21 + 4. ill fix this

OpenStudy (calculusxy):

So now what you have is: 21 + 4(4) 21 + 16

OpenStudy (calculusxy):

Add those up to get your answer

OpenStudy (muscrat123):

@audieeeuniverse solve 21 + 16 = ur answer
