Use the distributive property to remove
the parentheses. then combine like terms
-5+5(x+4)
3m+2(5m-7)
4(6t+9)-10t
8k-6(3-2k)

SO It is easy to do it So lets see
-5+5(x+4)                  You can multiply 5 with x and with 4
-5+5x+20                  You have to subtract the like terms and keep the sign of the   15 + 5x                   larger number.

3m+2(5m-7)              You can multiply 2 with 5m and with 7
3m+10m-14              You have to combine like term.
13m-14

4(6t+9)-10t              You can multiply 4 with 6t and with 9
24t+36-10t                You have to combine like term. 
14t+36

8k-6(3-2k)              You can multiply 6 with 3 and with 2k
8k-18-12k            You have to combine like term. 
-4k-18
I hope it would help you lo

This is what i found “an explicit formula designates the nth term of the sequence, as an expression of n (where n = the term's location). it defines the sequence as a formula in terms of n. this example is an arithmetic sequence(the same number, 5, is added to each term to get to the next term).” i hope this you for what your looking for. can you plz mark me brainliest?
