Answer:
4
Step-by-step explanation:
3x-5=7x-21
3x-7x=5-21
-4x=-16 ( divide by -4 both sides)
x= 4
Draw a perpendicular segment from point C to the midpoint of AB. Using the trig sine function sin 80 = x/6 which gives 5.91 for the perpendicular segment. Using the formula A=1/2bh, A= 1/2 x5.91x2sqrt 2 A= 8.4
Answer:

Step-by-step explanation:
<u><em>The correct question is</em></u>
The slope-intercept form of the equation of a line that passes through point (-2, -13) is y = 5x -3. What is the point slope form of the equation for this line?
we have

This is the equation of the line in slope intercept form
where
the slope is 
the y-intercept is 
Remember that
The equation of the line in point-slope form is equal to

we have


substitute


I think the answer has something to do with math
Given:
the equation x^2 = 36
Let us evaluate the equation. This equation is a quadratic equation. The roots of this equation are +6 and -6.
To determine the roots of the equation, solve:
x^2 = 36
x = +6
x = -6
