You can rewrite it as
(2/3 )•(10^(13-8))= (2/3)• 10^5 ~ 0.67•10^5=
0.67•10•10^4= 6.7•10^4
Answer $6.7•10^4
Step-by-step explanation:
solution,
given
DF = 42
DE = 7x+1
EF = 4x-3
DE = ?
here,
or, DF = DE +EF
or, 42 = 7x+1+4x-3
or, 42 = 11x-2
or, 42+2 = 11x
or, 44/11 = x
or, 4 = x
then,
replacing value of x in DE
DE = 7x+1
= 7*4+1
= 28+1
= 29

Distance formula : sqrt ((x2 - x1)^2 + (y2 - y1)^2)
(2,16)...x1 = 2 and y1 = 16
(-3,5)...x2 = -3 and y2 = 5
time to sub and solve
d = sqrt ((-3 - 2)^2 + (5 - 16)^2)
d = sqrt ((-5^2) + (-11^2))
d = sqrt (25 + 121)
d = sqrt 146
d = 12.08 <=
