d=√((x2-x1)²+(y2-y1)²)

Using above formula

AB= 2

BC= 4

CD = 2

AD = 4

PERIMETER = AB+BC+CD+AD = 2+4+2+4= 12 units

Answer:

11. Not enough information

12. You can say DB = DC by SAA congruence rule and CPCTC (Corresponding parts of congruent triangles are congruent)

Step-by-step explanation:

For 12, you can say ΔABD≅ΔACD because they have a side in common (AD) and they have 2 congruent angles. Thus, you can use the SAA congruence criterion. Then, you can use CPCTC (Corresponding parts of congruent triangles are congruent) to say that DB = DC.

Hope this helps :)

Please some help for question 1
o-na [289]

Answer:

f (3) is equal to 31

Step-by-step explanation:

f (3) means that x is equal to 3 [hence f (x) ---> f (3)]

Plugin 3 into all the x values to solve:

4(3)^2 - 2(3) + 1

4(9) - 6 + 1

36 - 6 + 1

30 + 1

31

f (3) is equal to 31

What is 3/15 in a decimal
Damm [24]
Well, since 3/15 can be simplified to 1/5 by dividing the top and the bottom by 3, you would just need to find the decimal of 1/5 which is much more commonly recognized. it's .2 (becasue 1/10 would be .1 and 1/5=2/10 so .1x2=.2)

Please help answer this
saul85 [17]

Answer:

Option D.

Step-by-step explanation:

The given inequality is y\le -2x-2.

To graph this inequality, we need to graph the corresponding linear equation;

y=-2x-2

The intercepts are (0,-2) and (-1,0).

Plot these two points and draw a solid straight line through them.

We then test the inequality with the point (0,0).

0\le -2(0)-2.

0\le -2.

This statement is false.

So we shade the lower half plane to obtain the graph in option D.
