Answer:
b = 30
Step-by-step explanation:
The sum of the 2 angles above the line will equal the angle below the line
3b + b - 15 = 2b + 45
4b - 15 = 2b + 45 ( subtract 2b from both sides )
2b - 15 = 45 ( add 15 to both sides )
2b = 60 ( divide both sides by 2 )
b = 30
Answer:
The value of a which equation have 2 , - 
Step-by-step explanation:
Given expression as :
2 a - 4 x = 4 - a² × x
The equation lies in the interval ( - 8 , - 2 )
∵ equation lies in the interval , so it must satisfy the equation
So , 2 a - 4 × ( - 8 ) = 4 - a² × ( - 8 )
Or, 2 a + 32 = 4 + 8 a²
Or, a + 16 = 2 + 4 a²
So, equation can be written as :
4 a² - a - 14 = 0
Or, 4 a² - 8 a + 7 a - 14 = 0
Or, 4 a ( a - 2 ) + 7 ( a - 2 ) = 0
Or, ( a - 2 ) ( 4 a + 7 ) = 0
∴ a = 2 And -
Hence The value of a which equation have 2 , - Answer
Answer:
no
Step-by-step explanation:
Suppose the numbers of interest are x, x+2, x+4. If we divide x by 3, its remainder will be one of 0, 1, or 2.
If x mod 3 = 0, then x will be a multiple of 3, so won't be prime (unless x=3).
If x mod 3 = 1, then x+2 will be a multiple of 3, so won't be prime.
if x mod 3 = 2, then x+4 will be a multiple of 3, so won't be prime.
Hence the only three sequential odd numbers that are prime are 3, 5, and 7. There are no more such "triplet primes."
_____
Consequently, the name "prime triplet" is given to sequences of primes that have the largest and smallest differ by 6. The middle one differs from one of the other two by 2. It is conjectured there are an infinite number of that sort of prime triplet.
Answer:
x = 70
Step-by-step explanation:
Properties of a parallelogram.
1). Pair of opposite sides of a parallelogram are equal in measure and parallel to each other.
2). Opposite angles of a parallelogram are equal in measure.
3).Adjacent angles of a parallelogram are supplementary.
By the second property,
(2x - 30) = (x + 40)
2x - x = 30 + 40
x = 70
