Solve this question
++=30
please use these numbers
{1,3,5,7,9,11,13}​

answer: 180

step-by-step explanation:

12-2=10

20-2=18

10x18=180

use distributive property on all like terms and change your signs if you have a double negative or if you have positive/negative

1. 16.64

a^2+b^2=c^2

pr^2=pq^2+qr^2

pr^2=14^2+ 9^2

pr^2=196+81

pr= sqr root of 277

16.64

2. 11.31

c^2-a^2=b^2

18^2- 14^2=b^2

b^2=324-196

b=sqr root of 126

b=11.31

hope it ! (btw im in connections academy to, good luck! )

time is equal to distance over rate so

t = d/r

need a little bit more information for the second question.
