All you do is add up the sides of the walls, and you get your answer.

Answer:
B
Step-by-step explanation:
L = 3x + 2
W = 2x - 3
Area = L * W
Area = (3x + 2)(2x - 3) Use FOIL to expand.
F (First): 3x * 2x = 6x^2
O (Outside): (3x)( - 3) = - 9x
I (Inside): 2 * 2x = 4x
L (Last): 2*(-3) = - 6
Answer = F + O + I + L
Answer = 6x^2 - 9x + 4x - 6 Reduce
Answer = 6x^2 - 5x - 6
Answer: B
Move all the number terms to one side and the X terms to the other. Then Add or Subtract it after that If there is still a number attached to the X term Divide it on both sides. This will reveal the answer.
Hello from MrBillDoesMath
Answer: + 4/7, 6 (13/14)
Discussion:
Let L be the larger of the two numbers and S the smaller of the two. Then the first sentence translates into this:
-6L - L = -4 =>
-7L = -4 => (divide both sides by -7)
L = - (-4)/(-7) = + 4/7 (*)
The second sentence translates to
2 (L + S) = 15 => (divide both sides by 2)
(L +S) = 15/2 => (subtract L from each side)
S = 15/2 - L = 15/2 - 4/7 (using (*) above)
So
S = 15*7/(2*7) - (4*2)/(7*2) (combine over common denominator of 14)
S = 105/14 - 8/14 = 97/14 = 6 13/14
Something is crazy here! While 2(L +S) = 15 -- check it out -- our larger number L ( =4/7) is actually smaller than the S number (6 13/14)! Maybe I should have called them Y and X, respectively, as you suggested!
Thank you,
Mr. B
Y = 60 degrees
Because alternate interior angles are congruent
