Answer:
8x+4 and 10x+4
Step-by-step explanation:
Using the distributive property, you times 8 by x and then 8 by one half: 8x & 8*1/2. 8x+4
You then do the same for 10(x+2/5): 10x and then 10 divided by 5 and times by 2. This leaves you with 10x+4.
I hope this helped. :)
Answer:
RT=75/4= 18.75
Step-by-step explanation:
RS+ST=RT
x+6+8=5x-5
4x=19
x=19/4
RT=5x-5
RT=5(19/4)-5
RT=95/4-20/4
RT=75/4= 18.75
