Answer:
Step-by-step explanation:
You need to use the quadratic equation
x =
Givens
- a = 1
- b = - 5
- c = 3
x =
x =( 5 +/- sqrt(25 - 12) ) / 2
x = (5 +/- sqrt(13) )/2
x = (5 + sqrt(13) / 2
x = 4.303 rounded
x = (5 - sqrt(13) ) /2
x = .6972
Answer:
square root (50) = 7.071
Step-by-step explanation:
Using Pthagoras' theorem, the diagonal length is .
Therefore, the diagonal length is the square root of 5^2+5^2,
=
=
= 7.071
