Answer:
3 inches
Step-by-step explanation:
if she cut 3 inches off the length, that makes it 9 inches. the original rectangle was 2 inches longer. so subtract 2 from 9 and 7. she needs to have the width 7 inches.
1.5 because you do -16=-8x-4
+4 +4
-------------------------------------------------------
-12=-8x
---------------------------------------------
- 8 -8
-12/-8 equals 1.5
2+2-37-9+23-6+78-34+89 = 149

Multiply both sides by 3
2x = -60
Divide both sides by 2
x = -30
The answer is B) -30
Hope this helps!
