Answer:
A. 4x¹² + 9x⁷ + 3x³ -x
Step-by-step explanation:
Hi!
<em>==================================================================</em>
To write a polynomial in descending order, we write the terms with higher degrees, or exponents, first.
3x³ + 9x⁷ -x + 4x¹²
4x¹² has the highest degree, so it is written as the first term.
⇒4x¹²
9x⁷ has the next highest degree, so it is written next.
⇒4x¹² + 9x⁷
3x³ has the next highest degree, so it is written next.
⇒4x¹² + 9x⁷ + 3x³
-x has the lowest degree, so it is written last.
⇒4x¹² + 9x⁷ + 3x³ -x
<u>4x¹² + 9x⁷ + 3x³ -x</u>

Answer:
3 (28 n - 9)
Step-by-step explanation:
Simplify the following:
-9 (1 - 10 n) - 2 (3 n + 9)
-9 (1 - 10 n) = 90 n - 9:
90 n - 9 - 2 (3 n + 9)
-2 (3 n + 9) = -6 n - 18:
90 n + -6 n - 18 - 9
Grouping like terms, 90 n - 6 n - 18 - 9 = (90 n - 6 n) + (-9 - 18):
(90 n - 6 n) + (-9 - 18)
90 n - 6 n = 84 n:
84 n + (-9 - 18)
-9 - 18 = -27:
84 n + -27
Factor 3 out of 84 n - 27:
Answer: 3 (28 n - 9)
Yes, set up your proportion: x/21 = 10/14
Cross multiply 14x = 210
Divide both sides by 14 and x= 15 cm
The anser is C for reasons of science ;)
If they are supplementary then 3x + 17x = 180
20x = 180
x = 9
m<GHI = 27 degrees
m < LMN = 153 degrees
