F(x) = -5x
g(x) = 8x² - 5x - 9
(f×g)(x) = ?
= ((-5x)(8x²-5x-9))
= -40x³ + 25x² + 45x → The answer Opsi D
Answer:
Step-by-step explanation:
ratio of 216 : 64
bigger is 20 inches
so divide 20 by 216... to find the unit.. then multiply that by 64 to find the size of the other
20/216 = 0.0925925
0.0925925 * 64 =5.9259"
so about 6 inches
and Hi :D
Since they're linear pairs, it would be x+134=180. so x = 46 degrees.
