You just need to replace the value of x and y in your expression. This gives us :
-12 * 5 - 4 * (-3) + 19 - 3*(-3) = -60 - (-12) + 19 - (-9) = -60 + 12 + 19 + 9 = - 20
Good luck for the next ones

Answer: A. 62.7
Step-by-step explanation:
Using the Pythagorean Theorem, know the distance from the top of the tower to the spot on the ground 750 feet away is 1636 feet.
Now with all lengths of the triangle we can solve for the angle giving us 62.7169723304
Now we round to the tenth as instructed and get an answer of 62.7
X = longest side , y = middle side , z = shortest side
P = x + y + z
P = 82
x = 2z + 7
y = z + 15
82 = (2z + 7) + (z + 15) + z...combine like terms
82 = 4z + 22
82 - 22 = 4z
60 = 4z
60/4 = z
15 = z
so the shortest side (z) is 15 cm
the second side (y) is : z + 15......15 + 15 = 30 cm
and the longest side (x) is : 2z + 7.....2(15) + 7 = 37 cm
First, subtract the 14 over
divide 3 by 29
g= 3/29 or
