Answer:
(x²+5) (x-3)²
Step-by-step explanation:
x³ - 3x² + 5x - 15
x²(x-3) + 5(x-3)
(x²+5) (x-3)²
9•10^4 / 3•10^3 = 30.
The whale has 30 times the mass of the elephant, or 29 times more. For that reason, it's 29 times heavier than the elephant.
The line with 37, x and 53 above it is straight meaning that it has an angle of 180. From this we can subtract the 37 and 53 that we have to find x.
x=180-(37+53)
Hope this helps :)
