All values increase by a scale factor of 10.
f(x)= x+10
Answer:
4(x) + 4(2)
Step-by-step explanation:
4(x+2) = 4(x) + 4(2)
Distribution property
Answer:11 honestly have no idea but im going to give my best answer it is 31
If we multiply the bottom equation by 2 and move x to the right, it becomes:
4y = 2x-38
Now we can substitute it for the 4y in the top equation:
3x + (2x-38) = -23 => 5x = -23+38 => 5x = 15 => x=3
Then 4y = 2*3-38 => y = -8
So the solution is (3,-8)
The perimeter is the distance all the way around. So it's the sum of the lengths of all 4 sides.
From the picture, you can clearly see the lengths of all 4 sides.
Writum down and adum up !
