Find the missing length indicated.
A) 48
B) 36
C) 100
D) 64
The answer is D) 64
(Not asking, just informing)

Option D: 64 is the length of x

Explanation:

The altitude of the triangle is 48

The two segments of the triangle are x and 36

From the figure, it is obvious that the altitude drawn from the right angle to the hypotenuse divides the hypotenuse into two segments.

Thus, by similar right triangles, we have,

Multiplying both sides by x, we get,

Simplifying, we have,

Multiplying both sides of the equation by 48, we get,

Dividing both sides of the equation by 36, we have,

Thus, the length of x is 64.

Therefore, the missing length is 64.

Hence, Option D is the correct answer.

x= -3 and

step-by-step explanation:

to find the roots of a cubic, use division or factoring to find the factors then set equal to 0. as this is a difference of cubes, it factors into

where a is the cube root of .

here   this is 27 and the cube root of 27 is 3. so we write using the form:

.

set each factor to 0 and solve for x.

x-3=0

x=3

the quadratic expression does not factor and must be solved using the quadratic formula.

where a = 1, b=3, and c=9

this cubic has two complex roots.
