2(x - 4) - 4x = 0
2x - 8 - 4x = 0
-2x - 8 = 0
-2x -8 + 8 = 0 + 8 (add 8 both sides)
(divide both sides by -2)
x = -4
Hope this helps
Answer:
559.70 ft
Step-by-step explanation:
Let D be the distance between building and Bianca.
Height of building H = 150 ft
Let there be a triangle ABC where, AC = height of building H= 150ft, AB = distance between Alice and Bianca and BC = D and therefore, ∠ABC = 15°.
Now in Triangle ABC , tanB = AC/BC
therefore, tan15° = 150/D
D = 150/tan15° = 559.70 ft
Therefore, the distance between building and Bianca D = 559.70 ft
Answer:
f(3) = 12
Step-by-step explanation:
f(x) = 2x - 12 + 2x²
f(3) = 2(3) - 12 + 2(3)²
f(3) = 6 - 12 + 2(9)
f(3) = -6 + 18
f(3) = 12
Remember that x=3 is being substituted into the equation, so you can apply this to any function rule problem for any value of x.
F - 1.47
The largest box represents 100 small cubes or 1. The four pillars represent 10 and there is four of them so it is 40. Then, the individual cubes are 7. So, 1.47.
