Answer:
x=3/radical2,-3/radical2,3/4
Step-by-step explanation:
By factoring you get
4x(2x^2-9)-3(2x^2-9)=(2x^2-9)(4x-3)=0
x^2=9/2, x=3/4
x=3radical2/2, -3radical2/2 , 3/4

Answer:
(14a + 3, 21a + 4) = 1
Step-by-step explanation:
Step-by-step explanation:
To prove that the greatest common divisor of two numbers is 1, we use the Euclidean algorithm.
1. In this case, and applying the algorithm we would have:
(14a + 3, 21a + 4) = (14a + 3, 7a + 1) = (1, 7a + 1) = 1
2. Other way of proving this statement would be that we will need to find two integers x and y such that 1 = (14a + 3) x + (21a + 4) y
Let's make x = 3 and y = -2
![(14a+3)(3) + (21a+4)(-2)\\42a+9-42a-8\\1](https://tex.z-dn.net/?f=%2814a%2B3%29%283%29%20%2B%20%2821a%2B4%29%28-2%29%5C%5C42a%2B9-42a-8%5C%5C1)
Therefore, (14a + 3, 21a + 4) = 1
Answer:
C
Step-by-step explanation:
I think this means you want the secant between 0 and 90 degrees.
The Secant(theta) = 1/Cos(theta)
Cos(theta) = 2/3
1/cos(theta) = 1//2/3 = 3/2
Answer: C
