A. 7n+2 = 4n+17 B. 10-d = -34-5d

C. 8(x-1)-2x = -(x+50)

D. 80-3k = 5k+8

E. 3(2x+3)-x = x-23

F. 12(y+5) = 13y+58

G. 6(x-1) = 9(x-4)

H. 4(w-6) = 3(w+1)

I. 3+2(8-k) = 3k-1

J. 9m = 4m-35

K. 7-6u = 5u+29

L. 8y-3 = 16-(1-2y)
this is an answer worth answering cuz youll get like 40 points or 80

a)n=5

b)d=-11

c)x=-6

d)k=9

e)x=-8

f)y=2

g)x=10

h)w=27

i)k=4

j)m=-7

k)u=-2

l)y=3

step-by-step explanation:

there is a formula i can give you:

it is r^2*n*sin(360/n) divided by 2 where r represents the "radius" and n is the number of sides.

plug them in:

(10sqrt(3))^2*6*sin(360/6) divided by 2

100*3*6*sin(60) divided by 2

900*sin(60)

900*sqrt(3)/2

450*sqrt(3)

approx is 779.4 cm^2

3x + 4y -25 =0 represents the amount of change sianna should recieve
