3x + 7x = 90
10x = 90
x = 9
Answer is 7 ×9 and 3 ×9
63 and 27
All three medians of a triangle intersect at the same single point. This is a point of concurrency known as its <em>centroid</em>.
Knowing that we have these three medians of a triangle, and the intersection of two of them is at (2, 3), the intersection of <em>any </em>pair of those medians would be at the same exact spot.
CD intersects AE at (2, 3).
5x - 4
4 less than = - 4 (since it's 4 less than and not 4 more than, the - 4 will go after five times a number)
five times a number = 5x (x because we don't know the number, so we use a variable)
Well you could factor out the 2 in the equation
6=3*2
10=5*2
4=2*2
so
6x^2-10x+4=2(3x^2-5x+2) so
factor 3x^2-5x+2 and get
(x-1)(3x-2)=0
so xy=0 then x and/or y=0 so
x-1=0
x=1
3x-2=0
3x=2
x=2/3
x=1 or 2/3
