Answer:
A. 6x + 4
B. 22 cm
Step-by-step explanation:
The perimeter of the triangle is equal to the sum of all the side lengths, which is (2x+3) + (x+1) + (3x), or 6x + 4.
When x = 3cm, the perimeter is 6(3) + 4, which is 22 cm.
I think I know what you might be asking for but could you lease clarify because the question is a bit hard to read.
Since the positive 4 is the on the y-axis and is changed to a -7 which is a smaller number than positive 4 the graph would be shifted down
