Answer:
The final answers are x = 10.385 OR x = -0.385
Step-by-step explanation:
Given the equation is x^2 -4 = 10x
Rewriting it in quadratic form as:- x^2 -10x -4 = 0.
a = 1, b = -10, c = -4.
Using Quadratic formula as follows:- x = ( -b ± √(b² -4ac) ) / (2a)
x = ( 10 ± √(100 -4*1*-4) ) / (2*1)
x = ( 10 ± √(100 +16) ) / (2)
x = ( 10 ± √(116) ) / (2)
x = ( 10 ± 10.77 ) / (2)
x = ( 10 + 10.77 ) / (2) OR x = ( 10 - 10.77 ) / (2)
x = 20.77/2 OR x = -0.77/2
x = 10.385 OR x = -0.385
Hence, final answers are x = 10.385 OR x = -0.385
Answer:
The Red Submersible
Step-by-step explanation:
Answer: 7.2
Step-by-step explanation:
The measures of the angles in a triangle always add up to 180°, so the answer is: m+p+n=180°.
<span>A geometric plane is two-dimensional. Standing at one point in the plane and picking two directions to travel which are not opposites of one another, any direction of travel on the plane can be obtained by composing these two directions. Since it is two directions, the plane is two-dimensional.
There is a way of describing this also using algebra. The general equation for a plane is ax + by + c = 0. For example, when a = 2, b = 3, and c = 4, the equation 2x + 3y = 4 is that of a plane. Since there are two variables here, x and y, the plane is two-dimensional.</span>
