The perimeter of the triangle is 13.56 units.
The perimeter of a shape on a coordinate plane is found by finding the distance between all points, and then adding them together. It's easier to write it out than to type so I'll attach a photo of my work.

i got to this by multiplying 30 and 65
Answer: A) The x-intercept decreases.
Step-by-step explanation:
Hi, for the function f(x) = mx + b, if the value of b decreases, but the value of m remains the same, The x-intercept decreases.
For example
For b=2, m =1 and x =0 (since the y-value of a linear equation when it crosses the x-axis is 0 )
f(x) =0(1)+2 =2 (x-intercept)
For b= 1 (b decrease)
,m =1 and x =0
F(x) = 0(1) +1 = 1 (x_intercept also decreases)
So, the correct option is A) The x-intercept decreases.

Answer:

given:
distance between two points formula:

using the formula:





12(x+3)=4(2x+9)+4x
12x+36=8x+36+4x
12x+36=12x+36
12x=12x
0=0
true for all x
