Step-by-step explanation:
there is no mathematical problem to solve.
just follow the instructions as given.
this is an exercise for you to get a feeling about what is what. it is imperative that you do it.
there is really nothing to solve.
remember, that a positive slope means the line goes up (from left to right), and a negative slope means the line goes down (again from left to right).
and I am sure you know what vertical and horizontal means.
Answer:
Value of x is 80 and yes they are vertical
Step-by-step explanation:
The answer is D because the other answers are all correct.
Isolate the B. Note the equal sign. What you do to one side, you do to the other. Subtract C and A from both sides
B + A (-A) + C (-C) = D (-A) (-C)
B = D - A - C
B = D - A - C is your answer

Perimeter is the sum of all outside dimensions.
Solve for x first:
12 + x+7 + x+2 + 5 + x +4 + x + 4 = 42
Combine like terms:
4x + 34 = 42
Subtract 34 from both sides:
4x = 8
Divide both sides by 4:
X = 2
Now solve for EF by replacing x:
EF =. X + 7 = 2 + 7 = 9 feet.
