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
