Answer:

4000 cgs

Step-by-step explanation:

This one requires 2 sets of brackets. You are best to work in grams.

1 dg = 10 grams

1 cg = 0.01 grams.

I wouldn't fret about this if I were you. This is the first time I've actually used these units. Most likely if you really need them, you can just look them up.

4 dg * [10 grams / 1 dg] * [ 1 cg / 0.01 grams]

40 grams * 1 cg / 0.01 grams

= 4000 cgs.

Notice the first set of brackets get's rid of the dgs

the second set of brackets gets rid of the grams.

The perimeter of the rectangle is 76 units. Find the length of side pq
larisa [96]

Answer:   PQ=16\ units

Step-by-step explanation:

The missing figure is attached.

The perimeter of a rectangle is:

P=2l+2w

Where "l" is the lenght and "w" is the width.

You can identify in the figure that:

w=SR=PQ=2z+2\\\\l=QR=PS=3z+1

Then, knowing the perimeter of the rectangle, you can make the subsitution into the formula:

 76=2(3z+1)+2(2z+2)

Now you must simplify and solve for "z"

76=6z+2+4z+4\\\\76-6=10z\\\\70=10z\\\\\frac{70}{10}=z\\\\z=7

Finally, substituting the value of "z" into  PQ=2z+2, you get:

 PQ=2(7)+2=16\ units

t1=2

t2=-8

r=t2/t1=-8/2=-4
