How do you solve these

Question

simplify and combine like terms

 

10.56 +4(8.2+4k)-2.36k

 

what is the value when

a= 16

b=4

c=3

 

a/b+c(c² +c )

 

Answer 1

10.56 + 4 *( 8.2+4k) -2.36k = 10.56 + 4*8.2 + 4*4k - 2.36k = 10.56+32.8+16k-2.36k=43.36 +13.64k

 

 

Part 2:

You just plug in the numbers with the corresponding letters in the equation:

16/4 + 3*(3^2+3)= 4 + 3*(9+3)= 4+ 3*(12) = 4+36=40
