Evaluate and match each expression on the left to its value on the right, when x = 9 and y = 6. 12 - x
x + 3y
4y - 10
1/3xy

12 - x= 3

x + 3y = 27

4y + 10 = 34

1/3xy = 18

Step-by-step explanation:

evaluating where x = 9 and y = 6

12 - x

12 - 9 = 3

x + 3y

9 + 3(6) = 9 + 18 = 27

4y + 10

4(6) + 10 = 24 + 10 = 34

1/3xy

1/3(9* 6 ) = 54 / 3 = 18

then, the surface area of the sphere shown in the image is: 256π sq. units!

step-by-step explanation:

the lateral surface area of a sphere is 2πrh where h=2r.

then:

surface area = 4πr^2.

in this case, r=8 units ⇒ surface area = 4π(8 units)^2. = 256π sq. units!

then, the surface area of the sphere shown in the image is: 256π sq. units!
