i think its 20 too, tho good luck

Answer:
Sydney is 14
Step-by-step explanation:
Sydney's age: n
Devaughn's age: 2n
Age together: 42
![2n + n = 42 \\ 3n = 42 \\ n = 14](https://tex.z-dn.net/?f=2n%20%2B%20n%20%3D%2042%20%5C%5C%203n%20%3D%2042%20%5C%5C%20n%20%3D%2014)
This means Sydney is 14.
Hope this helps! Brainliest would be appreciated :)
I feel like this too sometimes :(( it’s so tuff. i’m even one of the smarter people too and it just seems like there’s no end, but try to talk with your parents. tell them about this. it might not go well at first, but maybe they’ll understand eventually
Let's take these one at a time.
A
The A choice is that the y intercept of g(x) < y intercept of f(x). Remember, a y intercept occurs when x = 0
g(x) = 2 * sqrt(x) - 8
g(0) = 2*0 - 8
g(0) = - 8
=======
f(x) = - 4 when x = 0 (you just read it.) - 4 is greater than -8. That's a true statement. Think money. Would you rather be 4 dollars in debt or 8 dollars in debt?
A: True <<<<<< answer for A.
B
y intercept occurs when x = 0 The values of f(x) and g(x) have been found in part A.
Are they equal?
The y intercept of g(x) = g(0) = 2*sqrt(0) - 8 = - 8
The y intercept of f(x) = f(x) = - 4 when x = 0
Conclusion
They are not equal and B is not the answer.
C
The x intercept occurs when y = 0
g(x) = 0
0 = 2*sqrt(x) - 8
8 = 2*sqrt(x)
4 = sqrt(x)
x = 16
======
When f(x) = 0, x = 16.
Conclusion
The x intercepts are both 16. This statement is true.
C: True <<<<<< answer.
D
If the condition is anything but equal, the statement is false. g(x) is not greater then f(x).
D <<<<<< False.
Answer:
A=x(32-x)
Step-by-step explanation:
for a 32ft divider, e need to determine the length of the sides of the rectangular space. but since the length and breadth gives 32ft, we can express the side as
breadth= b,
length=x
x+b=32
b=32-x,
hence the area can be expressed as
A=l*x
A=x(32-x) unit square
the area expressed as a function of x is giving below
A(x)=x|(32-x)
