False, dilation changes the base and height of the triangle, forcing the area to change as well.
21 divided by 7 equals 3 and 3 x 7 is 21 the missing factor is 3 and the missing quotient is 21
It will look like this
There is no horizontal aseymtope, because it passes through all of possible y

Then we will multiply both sides of the equation by 2 π :
x + π ( 1 - x ) = 0
x + π - π x = 0
x ( 1 - π ) = - π / · ( - 1 )
x ( π - 1 ) = π
x = π / ( π - 1 )
The answer is -1/15 or 0.66666 well i think im not that good at math soooo sorry if its wrong
