Answer:
y = 4x + 8
Step-by-step explanation:
1) Find slope:
y2-y1/x2-x1
12-8/1-0 = 4/1 = 4
Slope = 4
2) Plug in a point in point-slope form
y-y1=m(x-x1)
y-8=4(x-0) =
y-8=4x-0 -> add 8 to both sides
y=4x+8
Answer:
b
Step-by-step explanation:
Because the triangles are congruent,
all their corresponding sides are equal,
so 2x-9=x+5, x=14
first side : x+5=14+5=19
second side: 15
third side: 8
P = 19+8+15= 42 Answer is D
The area of a square is: A = s^2
With side being s = 20m
A = 20^2m^2 = 400m^2
Hope that helps! :)
