Answer:
The order of rotational symmetry is 4.
X^6 + 3x^3......u have 2 terms making this a binomial
when u have one variable, the degree is the highest exponent of that variable...so this has a degree of 6
so u have a 6th degree binomial
Answer:
a² - b² = ± 32
Step-by-step explanation:
⇒ a + b = 4
⇒ a = 4 - b ... ( 1 )
Substituting this in another equation we get,
⇒ ab = -12
⇒ ( 4 - b ) ( b ) = -12
⇒ 4b - b² = -12
⇒ b² - 4b - 12 = 0
⇒ b² - 6b + 2b - 12 = 0
⇒ b ( b - 6 ) + 2 ( b - 6 ) = 0
⇒ ( b + 2 ) ( b - 6 ) = 0
⇒ b = -2, 6
Case 1: If b = -2
⇒ a = 4 - b
⇒ 4 - ( -2 ) = 4 + 2 = 6
Case 2: If b = 6
⇒ a = 4 - b = 4 - 6 = -2
Hence the numbers are 6 and -2.
⇒ a² - b² = ?
Case 1: a = 6 and b = -2
⇒ ( 6 )² - ( -2 )²
⇒ 36 - 4 = 32
Case 2: a = -2, b = 6
⇒ ( -2 )² - ( 6 )²
⇒ 4 - 36 = -32
Hence the answer for a² - b² can be ± 32 depending on the values of a and b.
hope it help a little bit.

Step-by-step explanation:
Admission price for an adult ticket and a student is $14 & $6 respectively .
<u>Step-by-step explanation:</u>
Here we have , A group who of 3 adults and 10 students paid $102 for a cavern tour. Another group of 3 adult and 7 students paid $84 for the tour .
Linear equation for statement A group who of 3 adults and 10 students paid $102 for a cavern tour:
⇒ 
, where x is price of adult ticket & y of students .
Linear equation for statement Another group of 3 adult and 7 students paid $84 for the tour :
⇒ 
, where x is price of adult ticket & y of students .
subtracting both linear equation we get:
⇒ 
⇒ 
⇒ 
Putting value of y in equation :
⇒
⇒ 
⇒ 
⇒ 
∴ Admission price for an adult ticket and a student is $14 & $6 respectively .
