Answer:
y=25
Step-by-step explanation:
y=4+4x+x^2
x=3
y=4+4(3)+(3)^2
y=4+12+(3)^2
y=4+12+(3x3)
y=4+12+(9)
y=16+9
y=25

Answer:
The Answer is C
Step-by-step explanation:
Look at each coefficient next to the degree of the radical. When inputting that number for synthetic division (From greatest degree to least) you would get 8 1 and -5. The number that is the divisor is the 6, but you have to set (x - 6) to equal zero, which would get you a number of 6.
To determine x intercept, put y=0
<span>x^4 - 10x^2 + 9
= 0
</span>
<span>x^4 - 9x^2 - x^2 + 9
= 0
x^2(x^2 - 9) - 1(</span><span>x^2 - 9) = 0
(</span><span>x^2 - 9)(x^2-1) =0
x^2 - 9 = 0
⇒ x^2 = 9
⇒x = +3, -3
x^2 - 1 = 0
x^2 = 1
x = +1, -1
X intercepts are -3, -1, 1, 3

First, we add the numbers. This gives us 715.
Then, we divide it by the amount of numbers. This gives us. 715 divided by 11.
This simplifies to 65.
