Answer:
The value of polynomial for x = 2 that is f(2) will be 32
Step-by-step explanation:
We have given polynomial 
We have to find the value of f(2)
We have to find the value of polynomial for x = 2
So for finding this value we have to just put x = 2 in polynomial
So f(2) will be 
So the value of polynomial for x = 2 will be 32
Answer: Explanation: 102=2⋅51. i102=(i2)51=(−1)51=−1.
Step-by-step explanation:
<h3>Given :-</h3>
- Perimeter of triangle = 42
- Side 1 of triangle = (x + 4)
- Side 2 of triangle = (3x + 8)
- Side 3 of triangle = (5x + 6)
<h3>To find:-</h3>
<h3>Explanation:</h3>
So to find length of sides we have to find the value of x.We can find value of x , by this formula:



So:-






















- Side 1 of triangle = (x + 4)
- Side 1 of triangle =2.67 + 4
- Side 1 of triangle = 6.67
- Side 2 of triangle = 3x + 8
- Side 2 of triangle = 3 × 6.67 + 8
- Side 2 of triangle = 20.01 + 8
- Side 2 of triangle = 28.01
- Side 3 of triangle = 5x + 6
- Side 3 of triangle = 5 × 2.67 + 6
- Side 3 of triangle = 13.35 + 6
- Side 3 of triangle = 19.35

We know that 3 point can creating always a plane
so from this result the right choice is A. so is true
X^2 - 8x-9=0
D = b^2- 4*a*c = 64- 4* (-9) = 64+36=100 =10^2
X1 = (8-10)/2 = -1
X2= (8+10)/2= 9
