13)
simplify.
(m + 11) + (n + 44)
a) m + n + 84
b) m + n + 55
c) mn + 55
d) mn + 484

B)m + n + 55

Step-by-step explanation:

it is really not that hard

B

Step-by-step explanation:

( m + 11 )  +  ( n + 44 )  =  m  +  11  +  n  + 44   = m  +  n  +  11  +  44  =  m  +  n  +  55

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth

step-by-step explanation:

the terms of a geometric sequence can be found by beginning with the first term and multiplying by the common ratio repeatedly. a recursive formula for a geometric sequence with common ratio r is given by an=ran−1 a n = r a n − 1 for n≥2 n ≥ 2 .
