Answer:
(c) 27x^11 +51x^7 +9x^6 -60x^5 +17x^2 -20
Step-by-step explanation:
As with many multiple-choice questions, you only need to look at something that will discriminate the correct answer from the wrong one.
The highest-degree product term is the product of the highest-degree terms in the factors:
(3x^5)(9x^6) = 27x^11
This matches choice C only.

In case you're interested in actually performing the rest of the multiplication, the distributive property applies.
(1 +3x^5)(17x^2 +9x^6 -20)
= 1(17x^2 +9x^6 -20) +3x^5(17x^2 +9x^6 -20)
= 17x^2 +9x^6 -20 +51x^7 +27x^11 -60x^5
Writing these terms in order of decreasing exponents gives ...
= 27x^11 +51x^7 +9x^6 -60x^5 +17x^2 -20
Answer:
hi lol
Step-by-step explanation:
Answer:
idk math lol sorry for wasting ur time
Step-by-step explanation:
Answer:
(1)
√(10^2 - 6^2) = 8
SIN(A) = COS(B) = 6/10
COS(A) = SIN(B) = 8/10
(2)
√(9^2 - 5^2) = 2·√14
SIN(A) = COS(B) = 2·√14 / 9 = 2/9·√14
COS(A) = SIN(B) = 5/9
