Answer:
-60
Step-by-step explanation:
first you have to input 4 to the equation g(x).
2(4) + 2(4) = 16
now input it to f(x)
-4(16) + 4 = -60
i feel like this is correct
Given:
.
To find:
The value of x.
Solution:
In triangles ABC and ADE,
(Right angles)
(Common angles)
(AA property of similarity)
We know that the corresponding sides of similar triangles are proportional. So,
On cross multiplication, we get
Therefore, the value of x is 
units.
[6] ([3] + [50])
Just make sure you understand how to work backward with problems like this if you are ever confused. :)) good luck!!
The correct answer is b. if you would like to know why, let me know (:
Answer:
n=15
Step-by-step explanation:
5(n+1)=2n+20
U start by expanding the first term which will give you 5n+5
Then after that u collect like terms giving u
5n-2n=20-5
Finally u evaluate it giving u
n=15
