Answer:
x=5
Step-by-step explanation:
2x+1=11
-1 -1
2x=10

2 2
x=5
(f∘g)(3) = f(g(3))
Find g(3) by substituting x=3 in g(x)
g(x)=x²-1
g(3)=3²-1
g(3)=9-1
g(3)=8
f*g(3) = f(g(3)) = f(8)
find f(8) by substituting x=8 in f(x):
f(x)=2x+3
f(8)=2(8)+3
f(8)=16+3
f(8)=19
So f∘g(3) = 19
Sorry I am wrong

it looks great! i'd give you an a+
honestly I couldn't make that
Answer:
2 units
Step-by-step explanation:
Given data
The points are (2, 3) and (2, 5)
x1= 2
y1= 3
x2= 2
y2= 5
substitute into the distance between two points formula
d=√((x_2-x_1)²+(y_2-y_1)²)
d=√((2-2)²+(5-3)²)
d=√(2)²)
d=√4
d= 2 units
Hence the length is 2 units
