Answer: x= -1, 3

Step-by-step explanation:

$x^2 -2x -3=0$

It is asking what is x when y is 0, so find the x-intercepts

to solve by graphing: type equation into desmos or a graphing calculator(<em>Y=, GRAPH</em>)

the points of intersection with the x axis are (-1,0) and (3,0)

so x=-1, 3

The largest angle in a triangle is three times as big as the smallest angle, and the middle angle is twice as big as the smalles

PtichkaEL [24]

Let X = smallest angle
largest 3x
middle=2x. add the 3 angles of any triangle and you get ,180

x+2x+3x=180
6x=180
x= 30
smallest =30
middle=60
largest=90

How can you express (15 30) as a multiple of a sum of whole numbers with no common factor?

Alex_Xolod [135]

Well theoretically speaking you could but that would take a long time and 15 and 30 have a common factor of 5 and 15. So I think for this one you can't since there are two common factors.
