B is the right answer because a is too short and c and d are too long
Answer:
Step-by-step explanation:
Since perimeter, 
and we know that P=2(l+w) then 
The length will be 
Now 
B, because the mid segment is half the length of the third side
Answer:
$y=(7/2)x+20$
Step-by-step explanation:
SInce the gradient of the first line is $-2/7$ then the gradien of the perpendicular line is $7/2$.
Therefore by the point slope formula the line that we are looking for is
$y-6=(7/2)(x+4)$
$y=(7/2)x + 20$
<span>x -3y=6
3y = x - 6
y = x/3 - 2
answer
</span>slope-intercept form of the equation: y = x/3 - 2
