See the following :)

First, you need to expand the brackets.

#5(d+3)+3(d-2)#
#=d*5+3*5+d*3-2*3#
#=5d+15+3d-6#

Then, you can group the like terms together as the following:

#=(5d+3d)+(15-6)#
#=8d+9#

Here is the answer for the question. Hope this can help you :)

#8d+9#

#5(d+3)+3(d-2)#

first, distribute the 5. that means multiply the five by everything inside the parentheses.

#5d+15+3(d-2)#

then, distribute the 3

#5d+15+3d-6#

finally, combine like terms

#8d+9#
