Answer: 30
We will 5x+3x=48 simplified it’s 8x=48 divide 8 from both sides and get x=6 plug it in
RS= 5(6)= 30
Answer:
x=-5

Answer: 15
Step-by-step explanation:
=(−5−4)2+(−4−8)2‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾√
d=(−5−4)2+(−4−8)2
=(−9)2+(−12)2‾‾‾‾‾‾‾‾‾‾‾‾‾‾√
d=(−9)2+(−12)2
=81+144‾‾‾‾‾‾‾‾‾√
d=81+144
=2‾√25
d=225
=15
