3x^2+9x-54
= 3(x-3)(x-6)
That’s your answer 3(x-3)(x-6)

The answer is 3(x - 3)(x + 6)

Factor common term from 3x^2 + 9x - 54
In this case, 3 is the common term. Hence:
  3(x^2 + 3x - 18)

Simplify by factoring (x^2 + 3x - 18). Hence:
 (x - 3)(x + 6)

Therefore: 3(x - 3)(x + 6)

A telephone pole has a wire to its top that is anchored to the ground. The distance from the bottom of the pole to the anchor po
Bumek [7]

Answer:

The height of the pole is 105ft,

Step-by-step explanation:

Let us call h the height of the pole, then we know that the distance from the bottom of the pole to the anchor point is 49, or it is h - 49.

The wire length d is 14 ft longer than height h, hence

d= h+14.

Thus we get a right triangle with hypotenuse d= y+14, perpendicular  h, and base h-49; therefore, the Pythagorean theorem gives

(h-49)^2+h^2 = (h+14)^2

which upon expanding we get:

h^2-98h+2401 = h^2+28h+196

further simplification gives

h^2-126h+2205=0,

which is a quadratic equation with solutions

h =21ft\\h = 105ft.

Since the first solution h =21ft will give the triangle base length of 21ft-49ft = -28ft which is negative; therefore, we disregard it and pick the solution h = 105ft.

Hence, the height of the pole is 105ft.
