Answer:
- sides: 12 feet
- front: 28 feet
Step-by-step explanation:
Let x represent the length of one side of the yard. Then the width of the yard is 2x+4, and the perimeter is ...
P = 2(L +W) . . . . . . . . . . formula for perimeter of a rectangle
80 = 2(x + (2x+4)) . . . . . with values from the problem filled in
40 = 3x +4 . . . . . . . . divide by 2, collect terms
36 = 3x . . . . . . . . . subtract 4
12 = x . . . . . . . . . divide by 3. This is the length of the side fence.
2x +4 = 2(12) +4 = 28
The fence is 12 feet on the sides and 28 feet on the front. (Its total length is 52 feet.)
Answer:
You just need to demonstrate that the expression is not equivalent. To do that, we just need to evaluate the expression with a specific number.
For 
, we have
Notice that the answer is true because 2 is not equivalent to 5.
Therefore, the expression is actually non-equivalent.
Answer:
Only C
Step-by-step explanation:
A = 3D
J = 7 + D
A: Alice doesn't necceserily have more stamps than Jane ( Jane could have 8 + 4 = 12 stamps, and Alice would have 3 + 4 = 7) (This is false)
B: Jane will ALWAYS have 7 more stamps than Doris (if all values are increased by same amount). (This is false)
C: The Sum of Alice and Doris is D + 3D = 4D, so C is true
