Answer:
(10,8)
Step-by-step explanation:
Symmetry over x axis: you keep x, but change the sign of y value.
So, the symmetric of (10,-8) is (10,8)
So it started at 180. After 4 more years it’s grown 188 cm to 368. If we estimate that it’ll grow 188 cm in another 4 years that puts our total to around 556. If we estimate and take off a year, it would probably be around 548 cm :)
So first off, remember the formula for the area of a rectangle. it's length time width right? or, you could think that A= 2 things multiplied together. how can we simplify x^2 - x -72 to equal two things multiplied together? well, we can factor it! We know that one of the factors is x+8 right? so what's the other factor? it would be x-9. so, we know width is x-9. I'm not sure if you need an actual value for width. if so, I could probably go further.
