The answer: 9 and 10 or 8 and 9
8x8=64
9x9=81
10x10=100
They are close by 18 so If it’s only an answer I would go for 8 and 9
Answer:
x=-4.73 x=-1.27
Step-by-step explanation:
(x + 3)^2 - 3 = 0
Add 3 to each side
(x + 3)^2 - 3 +3= 0+3
(x + 3)^2 = 3
Take the square root of each side
sqrt((x + 3)^2) =±sqrt( 3)
(x + 3) =±sqrt( 3)
Subtract 3 from each side
x + 3-3 =-3±sqrt( 3)
x = -3±sqrt( 3)
Approximating to 2 decimal places
x=-1.27 x=-4.73
Answer:
C
Step-by-step explanation:
f(x)=0 at points of intersection of the graph of the function with x-axis.
From the diagram you can see that the graph of the function intersects x-axis at three points:
somewhere between -3 and -2;
somewhere between -1 and 0;
at x=1.
Since x=1 is the value of x from the domain, then correct choice is option C.
Answer:
![3\sqrt[4]{5}](https://tex.z-dn.net/?f=3%5Csqrt%5B4%5D%7B5%7D)
Step-by-step explanation:
Given: ![\frac{\sqrt[4]{810} }{\sqrt[4]{2} }](https://tex.z-dn.net/?f=%5Cfrac%7B%5Csqrt%5B4%5D%7B810%7D%20%7D%7B%5Csqrt%5B4%5D%7B2%7D%20%7D)
Top and bottom has fourth root. so we take fourth root in common
![\sqrt[4]{\frac{810}{2} }](https://tex.z-dn.net/?f=%5Csqrt%5B4%5D%7B%5Cfrac%7B810%7D%7B2%7D%20%7D)
When we divide 810 by 2. we will get 405
![\sqrt[4]{405}](https://tex.z-dn.net/?f=%5Csqrt%5B4%5D%7B405%7D)
Now we simplify the fourth root
405 can be written as 3*3*3*3*5
![\sqrt[4]{3*3*3*3*5}](https://tex.z-dn.net/?f=%5Csqrt%5B4%5D%7B3%2A3%2A3%2A3%2A5%7D)
A.
k=x
j=7+x
4j=200
b. we need to know what jordan is first
4j=200
divide by 4 both sides
j=50
then
j=7+x
50=7+x
43=x
kim is 43
c. jordan is 50
