You add 9 to both sides to get:
<span>y – 9 + 9 = –17 + 9
</span>
so it's <span>Addition Property of Equality
answer
</span>B.Addition Property of Equality
The greatest area he can fence is 64 ft².
In order to maximize area and minimize perimeter, we use dimensions that are as close to equivalent as possible. 32 feet of fence for 4 sides gives us 8 feet of fence per side. We would have a square whose side length is 8; the area would be 8*8 = 64.
300 miles is equal to 528,000 yards
umm I think it =(m)(x+−x)
=(m)(x)+(m)(−x)
=mx−mx
=0
