Answer:
7
Step-by-step explanation:
56/2=28 (since the formula is w x l x 2)
28/4=7
Width is 7 inches and length is 21 inches.
7 + 21 = 28 x 2 = 56
Answer:
3
Step-by-step explanation:
4f-3 = 5f-6
First I would try to get the f's on one side and the other numbers on the other, to do this you woudl have to add 6 to both sides
4f -3 = 5f -6
+6 +6
Making it into: 4f + 3 = 5f
Now to get the 4f on the other side we will have to subtract it from both sides
4f +3 = 5f
-4f -4f
3= f (Remember you do not have to put the 1, making 3 your answer)
