Answer:
A, 52.5
Step-by-step explanation:
We see that the 42 side corresponds to the side with side length 16, so the factor is 42/16 = 21/8. Now, we are looking for the side that corresponds to x, which is 20. Multiplying by the scale factor, we have 20 x 21/8 = 52.5
You can do foil method first, to make it easier and to avoid product rule,
y= 45x^4 - 15x³ + 25x² - 72x² + 24x - 40
Simplify like terms,
y= 45x^4 - 15x³ - 47x² + 24x - 40
Now, find derivative,
dy/dx = 180x³ - 45x² - 94x + 24
2/20 = 1/10 = 3/30 = 4/40
so 3 equivalent ratios can be 1/10 (or 1:10), 3/30 (or 3:30), 4/40 (or 4:40)
