Answer:
13
Step-by-step explanation:
4a-2=4×2-2=6
6(2+4) =6×6+1
-3
4(2)-2(2+4)+1=8-2(6)+1=9-12=-3
We are given that the surface area A is:
A = 5.2 ft^2
To convert this into in^2, we know that there are 12 inches in 1 feet, so 12 in = 1 ft:
A = 5.2 ft^2 * (12 in / 1 ft)^2
<span>A = 748.8 in^2</span>
16/40 = 0.4
Find total marbles then divide the number of green by total.
This will help okay! I promise you, well I hope .
