9
Step-by-step explanation:
You could multiply the length that they have given you by 2 and subtract that from the perimeter. That gives you the total length of the missing side and divide it by 2 to get one side.
Answer:
d 5 =9^ y
Step-by-step explanation:
log9 (5) = y
If we have loga(b) =c then it becomes a^c =b
So 9^y = 5
I also think
Raise each side to the 9
9^(log9 (5)) =9^ y
That will get rid of the log9
5 =9^ y

Answer:
33 ft
Step-by-step explanation:
The perimeter formula for a rectangle is ...
P = 2(L +W)
Filling in the given numbers, we have ...
146 = 2(40 +W)
73 = 40 +W . . . . . . . divide by 2
33 = W . . . . . . . . . . . subtract 40
The backyard is 33 feet wide.
