Answer:
Step-by-step explanation:
∠DEF is congruent to ∠EFA
Step-by-step explanation:
since all 4 sides are equal in length, the figure is a square.
let the length of the square be lm.
529 = l x l
l = 23m
perimeter = 23 x 4 = 92m

M=-2/5 is the answer to this equation
D=rt
r=(boatrate+riverrate)=(x+2)mph
d=528ft=528/5280mi=1/10mi
t=1/3hr
remember to keep the same units
so
1/10=(x+2)(1/3)
times both sides by 3
3/10=x+2
minus 2 or 20/10
-17/10=x
-1.7=x
it would be going -1.7mph (means going backwards)
