Each of the triangles are equal in base length, height, and area. Remember the formula for the area of a triangle. The area of any triangle is 1/2 times the length of the base (which, in the polygon, is the length of a side) multiplied by the height (which is the same as the apothem in regular polygon)

I need help finding 13-22
Scrat [10]
13. (3/8)*q + 12 = 36
3q/8 = 24
3q = 192
q = 64

14. 3 - (3/4)n = 9
-3n/4 = 6
-3n = 24
n = -8

15. (7/9)v + 2 = 23
7v/9 = 21
7v = 189
v = 27

16. 7 + (1/8)l = -2
l/8 = -9
l = -72

17. (v/-3) + 8 = 22
v/-3 = 14
v = -42

18. 8x - 16 + 8x = 16
16x = 32
x = 2

19. 12a - 14a = 8
-2a = 8
a = -4

20. 7c - 8 - 2c = 17
5c = 25
c = 5

21. 6 = -y + 42 - 2y
-36 = -3y
y = 12

22. 16 + 8r - 4r + 4 = 24
20 + 4r = 24
4r = 4
r = 1

Algebra:Can someone help I don’t know where I went wrong but my answer is wrong
evablogger [386]

Hey there!!

3 ( x - 6 ) + 15 = 4 ( x - 1 ) + 4

3x - 18 + 15 = 4x - 4 + 4

3x - 3 = 4x

- 3 = x

x = -3

The mistake is , you have written -4 + 4 = 8

- 4 + 4 = 0

and - 18 + 15 = - 3 ( not - 33 )

correct it, you will get it

Hope helps!
