Answer:
13.42477795
Step-by-step explanation:
Answer:
First, let's address the general case.
When we have two points (a,b) and (c,d)
The distance between those points can be written as:
D = √( (a - c)^2 + (b - d)^2)
In this case, the points are:
(-2,4) and (2,4)
Then the distance is:
D = √( (-2 - 2)^2 + (4 - 4)^2) = √(-4)^2 = 4.
The equivalent expression to this is: |-2| + |2|
because:
I-2I = 2
I2I = 2
I-2I + I2I = 2 + 2 = 4.
Hey there!!
Given equation :
f ( x ) = x² + 2x + 1
Find f ( 2b )
In order to solve this question, we will need to replace the value 2b instead of x
... f(2b) = ( 2b )² + 2 ( 2b ) + 1
... f(2b)= 8b² + 4b + 1
Hope my answer helps!
2 (2x - (2 - 2y + 3x) + 4y) =
2 (2x - 2 - 2y + 3x + 4y) =
2 (5x + 2y - 2) =
10x + 4y - 4
This was my solution.
15x + 18y ≥ 120 would be the inequality
