Answer:
2-sqrt14/2, 2+sqrt13/2.
Step-by-step explanation:
What you do is you have to do the quadratic equation like it says in the problem.
x= −b± sqrtb^2 −4ac
/2a
.
a=-2, b=4, c=5.
x=-4±sqrt(4)^2-4(-2)(5)/2(-2).
x=-4±sqrt16+40/-4.
x=-4±2sqrt14/-2.
2-sqrt14/2, 2+sqrt13/2. is your answer once you have done everything.
14× 14 = 196 area of 1 of the squares. on a cube there are 6 squares so multiply 196 by 6
196 × 6 = 1176 sq in

Answer:
97/113
Step-by-step explanation:
67 robots have legs only, 21 have wheels only, and 9 have both legs and wheels. The total number of robots with legs and/or wheels is 97.
The probability is 97/113.
The length of the arc =R × theta
theta =the length of the arc /R
theta =16/19.36
that's what i know
