Answer:

40 in

Step-by-step explanation:

A= l x w

2 x 9 = 18

2 x 11 = 22

Then add together because the shape is together:

18 + 22 =

Answer:

17) m(slope) = -5

18) m = 1/3

19) m = -1/5

20) m = undefined

21) m = 1/4

22) m = -2/3

23) m = -1

24) m = -1

25) m = -2/3

26) m = -5/2

If 1+4=5, 2+5=12, 3+6=21 then 8+11=?

Answers

In this pattern, 8+11= 8+11 + 77 (the previous answer) = 96
As you go to the next step in the pattern, you add the previous answer as well, so:
1+4=5
2+5= 2+5+5= 12
3+6= 3+6+12 = 21
4+7= 4+7+21 = 32
5+8= 5+8+32 = 45
6+9= 6+9+45 = 60
7+10= 7+10+60 = 77
So 8+11= 8+11+77 +96

I'm not sure how to write this mathematically as such, only in a logical way, but I hope it helps!

Write the equation of each line in the indicated form 1. Standard form. Slope=8/3;(-2,0)

2. Point-slope form (-5,6) and(3,-10)

Answers

1. standard form is y=mx+b so I will use point slope to start
y-0=8/3(x+2), y=(8/3)x+(16/3)
2.Must solve for slope first, (y2-y1)/(x2-x1), -10--5/3-6= -5/-3= 5/3
so slope is 5/3, point slope is y-y1=m(x-x1), y-6=5/3(x+5)
