If you are asking for the perimeter of the bulletin board the answer below will be correct!
Answer:
Square option: 9.5 Meters
Rectangle option: see explanation below
Step-by-step explanation:
To find the perimeter you must add the lengths of all the sides. Assuming the bulletin board is a SQUARE all four sides are going to be equal. Therefore you can divide 38 by 4 to get the length of one side (aka 9.5 meters).
Assuming the bulletin board is a RECTANGLE changes things up. You can pretty much pick any combination of numbers that will add up to 19 (because if it is a rectangle there are two pairs of equal side lengths). You could do 1 + 18, 5+14, 8+11. The options are really endless
Answer:
D. X=7
Step-by-step explanation:
Use the order of operations to solve this problem.
First, combine like terms.
7x-5x=2x
Our equation is now 2x-3=x+4
Now, add 3 to both sides.
Our equation is now 2x=x+7
Subtract x from both sides.
x=7
The answer is D. X=7

Answer:
x=2
Step-by-step explanation:
First use the distributive property on the right side... You should get then have 7x+30 = 2 + 6x + 30
Simplify further by combining like terms to get 7x + 30 = 32 + 6x
Now subtract 6x on both sides (6x - 6x cancels out) to get 1x + 30 = 32
Next subtract 30 from both sides(30-30 cancels out) to get 1x = 2
2 divided by 1 is 2 so x = 2
