The answer would be 7,433,700
For example x^2=25
Without x the expression wouldn't exist, it allows you to calculate unknowns for example in a physics experiment using v=u+at
Graph y=-6x-3 you have to first simplify the equation. it looks more complicated than it is.
Step-by-step explanation:
The explanation is in the second photo
I think I have the diagram right.
Let ADB = x, and then BDC = x+32.
x+x+32 = 90
2x = 58
x = 29 = ADB
so BDC = 61
