To organize the expressions according to the number of terms, you should understand what a term is. A term is either a single number or variable, or numbers and variables multiplied together. Terms are separated by + or − signs. It is organized as follows:
2x2y + x2 - 3x + 4
3x + y + z
x + 2xyz
9x2yz
5. y = x + 7
6. y = -x + 1
First convert everything into inches.
1 foot = 12 in
5 feet = 5*12 = 60 in
12 feet = 12*12 = 144 in
Now add them together
60 + 9 + 144 + 3 = 216 in
or
18 feet
Hope this helps :)
