-7 + 10 = 3
=
10 + (-7)
Is the same as
10 - 8
…
Not sure if this was that helpful.. I hope it did.
Hello there!
See picture below...
Let me know if you have any questions about the answer. As always, it is my pleasure to help students like you!
560 ft^2
20ft x 10ft = 200 ft^2
+
12ft x 30ft = 360 ft^2
=
560 ft^2
8192, 16 x 8 x 64, 24 = 16, 26= 64, 23= 8
1 foot is 12 inches so 12*12=144in.
then you have to add 144+2= 146 inches
