3. 4 times x of a fence would 4x, and then you would put on the minus 3 for the first length of fence to be 4x-3. For the second length of fence, 5 times x would be 5x, adding on the 6 and you get 5x+6. Add these two equations together and you get the answer of A: (4x-3)+(5x+6).
4. Add both of the number of seeds in the garden, which is x+4x+10. By adding like terms, you get the new equation of 5x+10. Therefore, the total number of seeds that Val plants will be 5x+10.
