Finding how much fence Angela needs to put in garden can be found by finding the perimeter of the walls that are not blocked by anything. For example, the house is blocking one side of the garden.
We can write this expression as: 2x + 2x + x
After solving we get 5x.

Answer:
9.24 m to 2 DP's.
Step-by-step explanation:
Consider the right triangle formed from a side , altitude and 1/2 the base.
By pythagoras:
x^2 = 8^2 + (0.5x)^2 where x is the length of each side.
x^2 - 0.25x^2 = 64
0.75x^2 = 64
x^2 = 64/0.75 = 85.3333.
x = 9.2376 m.
Answer: B. x = 2/4
Reason:
The thing they need to share are the sandwiches (y), where x is the amount of sandwich per person, so that goes in the equation first.
4/2 is 2 so that doesn’t make sense.
C isn’t an option because there are 4 people in this word problem. Don and his 3 friends = 4.
D isn’t right because there’re 2 sandwiches, not 1.
Let's assume the cost 20 years ago equals x
3x - 3 = 75
or
x = 75 / 3 + 3
Answer:
i am pretty sure it is the last one
