By minusing 12 to both sides
d+12=2
-12=-12
d =-10
To factor the given function, find a term that is divisible by both terms. For this problem, the factor would be 2, since 2x^2 and -18 are both divisible by 2.
2(x^2 - 9)
You could further factor out x^2 - 9 because it is factorable by (x - 3) and (x + 3). Thus, it would be
2(x -3)(x+3)
I'm so sorry you have to take this X( I'm doing something really similar <3
Angle WXY is 100 degrees. You add angle WXZ and angle ZYX and you get 100. 60+40=100
