Answer:
The no. of variations in sign is 3
Step-by-step explanation:
Variation in sign occurs when every single time a negative product is produced by a pair of consecutive terms.
Therefore, the determination of the number of changes in sign in the given sequence is must.
Therefore, we take the product of the pair of consecutive terms as:
= - 3, variation in sign
= - 6, variation in sign
= 10, no sign variation
= - 20, variation in sign
= 24, no sign variation
X=7

Answer:
x=12
Step-by-step explanation:
The three angles add to a straight line which is 180 degrees
20 + 6x-2 + 90 = 180
Combine like terms
108 + 6x = 180
Subtract 108 from each side
108+6x-108 = 180-108
6x =72
Divide each side by 6
6x/6 = 72/6
x=12
