Divide the area of the banner by 4 and the perimeter by 4 as well P=39 A=374
Answer:
A
Step-by-step explanation:
Yes you can see the answer but you might need to watch an ad first then it will show you the answer
a is given to us so just plug a into the first equation:
b-3 - 3b =9
Add 3 to both sides:
b-3b=12
Combine like terms:
-2b=12
Divide by -2 to get b by itself:
b=-6
The only answer with b as -6 is the first one, (-9,-6)
