Answer:
X= 7, -2
Step-by-step explanation:
if ur asking for X but if yea that's the answer for X
- Um número => x
- O quadrado de um número => x²
<span>- O produto desse número por 3, mais 18 => 3x + 18
x</span>² = 3x + 18 => x² - 3x - 18 = 0, p/ a = 1, b = -3, c = -18
Δ = (-3)² - 4(1)(-18) = 81
<span>x' = [-(-3) + 9]/2 = 12/2 = 6
x" = </span><span> [-(-3) - 9]/2 = -6/2 = -3</span>
The midsegment of a triangle is a segment that connects the midpoints of two sides of the triangle.
A point is equidistant from two objects if it is the same distance from the objects.
The distance from a point to a line is the length of the perpendicular line segment from the point to the line.<span>
</span>When three or more lines intersect at one point they are they<span> are concurrent. The </span>point<span>at which </span>they intersect<span> is the </span>point<span> of concurrency.
</span>hope this helps
