Answer 1

\[\Huge{\color{red}{\bigstar}\color{blue}{\bigstar}\color{green}{\bigstar}\color{yellow}{\bigstar}\color{orange} {\bigstar}\color{red}{\bigstar}\color{blue}{\bigstar}\color{green}{\bigstar}\color{yellow}{\bigstar}\color{orange} {\bigstar}\color{red}{\bigstar}\color{blue}{\bigstar}\color{green}{\bigstar}\color{yellow}{\bigstar}}\\\color{white}{.}\\ \Huge\sf\color{blue}{~~~~Welcome ~To~ OpenStudy!~\ddot\smile}\\\color{white}{.}\\\\\Huge{\color{red}{\bigstar}\color {blue}{\bigstar}\color{green}{\bigstar}\color{yellow}{\bigstar}\color{orange}{\bigstar}\color{red}{\bigstar}\color{blue} {\bigstar}\color{green}{\bigstar}\color{yellow}{\bigstar}\color{orange}{\bigstar}\color{red}{\bigstar}\color{blue} {\bigstar}\color{green}{\bigstar}\color{yellow}{\bigstar}} \]
mmm you would use the distance formula
\[distance formula: \sqrt{(x _{2}-x _{1})^{2} + (y _{2}-y _{1})^{2}} \]when given points (x1, y1) and (x2, y2)
for each segment

Answer 2

i tried it but got a different answer i got 22 and the answer choice are
A.25.8 units
B. 26.1 units
C.27.5 units
D.28.6 units

Answer 3

yeah okay :) then I've got it :)

do QR + RS + ST + TU + UQ

QR = √(2^2 + 5^2) = √(29)
RS = √(4^2 + 2^2) = √(20)
ST = √(2^2 + 3^3) = √(13)
TU = √(1^2 + 4^2) = √(17)
UQ = √(3^2 + 8^2) = √(73)

so QR + RS + ST + TU + UQ
= √(29) + √(20) + √(13) + √(17) + √(73)

Answer 4

so would i turn them into decimal? since all the answer choices are in decimal form?

Answer 5

yep :)
