Answer:
Step-by-step explanation: it is 4:40
C^2 + 11c = 12
c^2 + 2[11/2] c = 12
[c + 11/2] ^2 - [11/2]^2 = 12
[c +11/2]^2 = 12 +[11/2]^2
[c +11/2]^2 = 12 + 121/4
[c +11/2]^2 =[48+121]/4
[c +11/2]^2 = 169/4 ----> This is the resulting equation
Solving it you get:
c + 11/2 = +/- √(169/4)
c + 11/2 = +/- 13/2
c = 13/2 - 11/2 =2/2 = 1 and
c = -13/2 - 11/2 = - 24/2 = -12
Answer:
choose b and d
distribute the number outside the parenthesis to each term on the inside of the parenthesis.
Answer:
2/3 - 1/4
=> taking L.C.M of the denominators we get,
=> 8/12-3/12
=> 5/12 is left with her,, ;)
HOPE THIS HELPS YOU...;)
Pythagorean theorem : a^2 + b^2 = c^2
using 3,4,5
3^2 + 4^2 = 5^2
9 + 16 = 25
25 = 25 (correct)
using 8,15,17
8^2 + 15^2 = 17^2
64 + 225 = 289
289 = 289 (correct)
they are Pythagorean triplets because they satisfy the Pythagorean theorem
