Answer: Hi!
First, we should combine like terms:
4b + 5b = 8b − 1 +3b + 15 =
9b = 11b + 14
Now, we should subtract 11b from both sides.
-2b = 14
Now, we should divide both sides by -2.
b = -7
Hope this helps!

Answer:
A,
Step-by-step explanation:
Use pythagoreaan theorem
a^2+b^2=c^2
a and b are teh legnth s of the legs
c is the legnt o fthe hyptonuse
8^2+13^2=c^2
64+169=c^2
233=c^2
square root both sdies
aprox 15.264=c
the legnth is aprox 15.26 cm
