d(-3 + x) = kx + 9

  • Distribute d within the parentheses:

-3d + dx = kx + 9

  • Subtract kx from both sides:

-3d + dx - kx = 9

  • Add 3d to both sides:

dx - kx = 9 + 3d

  • Factor x from dx - kx:

x(d - k) = 9 + 3d

  • Divide both sides by (d - k):

x = \frac{9+3d}{d-k}

  • To further simplify, factor 3 out of the numerator.

x = \frac{3(d + 3)}{d-k}

AnnZ [12381]
The height of the triangle measures 5.2 inches. An equiangular triangle has equal measures for all interior angles, which means it is equivalent to an equilateral triangle. Since all angles equal 60 degrees, applying the Pythagorean theorem enables us to calculate the height based on the provided side length.

minimum = 75
Q1 = 88.....this indicates the start of the box
Q2 (the median) = (90 + 96) / 2 = 186/2 = 93....this signifies the line within the box
Q3 = 98....this indicates the end of the box
maximum = 100
