If x+1/x=5 then find the value of (x^2+1/x^2) is?

based on context clues you gave i'm assuming the answer would be c.

c.

step-by-step explanation:

she should of added 9^2 and 12^2. that is because it is a^2+b^2=c^2. c^2 is the hypotenuse and should always be bigger than the other two numbers. which is why she should of added 9 squared and 12 squared together instead of 15 squared.

x=-7

step-by-step explanation:

x+3=-10

-10+3=-7

x=-7

-3.5 degrees per hour

step-by-step explanation:

find the unit rate:

-12   1/4 degrees           12.25 degrees

= - = -3.5 degrees per hour
