Answer:

Step-by-step explanation:

Add all the sides. But you are missing two sides. Soo since the top is 4, the bottom is two bc half is two. then the right side is 5 and the left, half is 2 so the other half is 3. 3+2=5! soooo the perimeter is 18.

Answer:

Step-by-step explanation:

We add up the side lengths,

$5+4+3+2+2+2= 18$

by finding missing side lengths with subtraction and logic

and I'm pretty sure this is correct, but I like double-checking things.

This figure is made out of 2 rectangles,

2x5 and 3x2

The perimeter of each is 14 and 10

$14+10-3-3=18$

the two 3's are the over lapping sides

We also get 18.

choose the equation in point slope form for the line that is perpendicular to the given line and passing through the given point

alexdok [17]

We want to determine the equation in point slope form for the line that is perpendicular to the given line and passing through the point (5.6) .

The equation and the point is;

$y=\frac{2}{3}x+9,(5,6)$

We know that for two lines to be perpendicular, the product of their slopes should be -1.

Therefore, the slope of the perpendicular should be;

$m=-\frac{1}{(\frac{2}{3})}=-\frac{3}{2}$

The second condition is that the line must pass through the point (5,6) , to do thid, we write the equation of the line in point slope form which is;

$y-y_1=m(x-x_{1_{}})$

Inserting all values, we have,

$y-6=.-\frac{3}{2}(x-5)$

That is the final answer.
