Let us try and solve it analytically. We have that the side=x+3 together with the short side=s and the diagonal=x+4 satisfy the Pythagorean Theorem. Then we have that

. This yields

which yields s^2=2x+7, hence a) is the correct answer.
Answer:

Step-by-step explanation:

Step 1: Divide the numbers

Step 2: Simplify

Step 3: Simplify

Therefore, the simplified answer is 
If you would like to know the length of each side of the patio, you can calculate this using the following steps:
an area ... 200 square feet
a ... the length of one side
area = a * a = a^2
200 = a^2
a = sqrt(200)
a = 14.14 feet
The correct result would be 14.14 feet.
Answer:
Step-by-step explanation:
A. False. The probability of drawing a green marble twice is even smaller (It may be true though depending on what the question is asking, if it is asking the chance of drawing a green marble second is the same as the 1st chance, then yes it is True.
B.False
C. False
D.True, 1/3*1/3 (Simplified version of 6/18*6/18) is 1/9
E. False (Although this may be true, again depending on the type of question)
F. False
Answer:
11
Step-by-step explanation:
x = -3
Substitute -3 with x

* = Multiplying
(-2*-3) + 5
= 6 + 5
= 11
