Answer:
x = ±2
Step-by-step explanation:
3x ^2 -4 = 8
Add 4 to each side
3x ^2 -4+4 = 8+4
3x^2 =12
Divide each side by 3
3x^2 =12
3x^2/3 = 12/3
x^2 = 4
Take the square root of each side
sqrt(x^2) = ±sqrt(4)
x = ±2
Answer with Step-by-step explanation:
We are given that
]
Average value of the function is given gy
Using the formula
Answer:
3x + 10
Step-by-step explanation:
9 + x + 1 + 2x
Combine like terms
2x + x = 3x
Combine like terms
9 + 1 = 10
We’re left with 3x + 10
The angle is 90 degree
So to find x we solve this equation:
2x + 38 = 90
2x = 90 - 38
2x = 52
x = 52/2 = 26
The value of x is 26
