Step-by-step explanation:
Distance = positive value
a + a = 2a
Answer:
B. x = 7, y = 4√2
Step-by-step explanation:
Drop a vertical from the upper left corner
This creates a rectangle and a 45-45-90 triangle
The bottom of the rectangle is 3
The legs of the triangle are 4
Therefor
x = 4 + 3
x = 7
For a 45-45-90 triangle
the hypotenuse = leg * √2
y = 4√2
Answer:
4y = -m-1 bcoz u use the formula y-y1 = (y2-y1/x2-x1) times (x-x1)
