5,12,13
5X5=25
12X12=144
25+144=169
answer: square root 169=13
If R is between Q and S then QR+RS=QS
given
QR=x+4
RS=3x-1
and QS=27
x+4+3x-1=27
combine like terms
4x+3=27
minus 3 both sides
4x=24
divide both sides by 4
x=6
sub back
QR=x+4
QR=6+4
QR=10
RS=3x-1
RS=3(6)-1
RS=18-1
RS=17
x=6
QR=10
RS=17
Answer is B) JK=9 and KL=10
you subtract 7 from 26 to get 19
A-10, D-11, F-8, I-2, G-1, K-9, B-7, C-3
That's what I got so far, but I'm still working
