B is 5, you can solve this by first finding the value of a, which is 2, and then plug it into the other equation. 8+2=10 so we must also make the other side 10. We then do 10-5=5, 5 is the value of b
So you need 2,3,4,5, and 6?
Brandon's rectangle:
Length = 8.75 x 1.5 = 13.125 inches
Width = 6 x 1.5 = 9 inches
If you need the area and perimeter then here:
Area = 13.125 x 9 = 118.123 inches square or sq in.
Perimeter = 2 x (13.125+9) = 44.25 in
Answer: 2
Step-by-step explanation: its just 2
