If x=5 and y=−2, evaluate the following expression:10+5xy​

-40

Step-by-step explanation:

You can replace the values of x with 5 and the values of y with (-2).

10 + 5xy = 10 + 5 × 5 × (-2)

              = 10 + 5 × (-10)

              = 10 + (-50)

              = -40

Step-by-step explanation:

10+5xy

[By putting the value of x = 5 and y = -2 ]

= 10 + 5 × 5 × (-2)

= 10 - 50

= -40 (Ans)

step-by-step explanation:

x^2 -12x + 36 + y^2 = 36

x^2 + y^2 = 12x

r^2 = 12rcos(theta)

r = 12 cos(theta)
