Answer:
20 cm
Step-by-step explanation:
Since it is a rectangle, we know that there are two pairs of sides the same length. All we have to do is add each number by itself, and add those numbers together, or you can envision it like this graph I made.
4+4=8
6+6=12
8+12=20
Answer:

Answer:
He was going 25 miles over the speed limit.

Answer:
y = -2/3x + 4/3
Step-by-step explanation:
If two lines are perpendicular, the product of their slopes is -1
comparing what we have with the general form;
y = mx + b
The slope of the given equation is 3/2
To get the slope of other;
3/2 * m = -1
3m = -2
m = -2/3
So we want to write the point-slope equation
y-y1 = m(x-x1)
y-2 = -2/3(x + 1)
3y - 6 = -2x -2
3y = -2x -2 + 6
3y = -2x + 4
y = -2/3x + 4/3
