9 over 16 times x over 12

x=6.75

Step-by-step explanation:

9/16x x/12

cross multiply

16 times x equals 16x 9 times 12 equals 108

16x=108

16/16=108/16

x=6.75

pls brainliest hope this helps

 so its 9/16 x x/12= x/192

Part A: Rectangle

Part B: Rectangle

Step-by-step explanation:

We are given a rectangular prism as shown.

Part A: After slicing the rectangular prism with a plane parallel to the base, we see that the cross-sectional region will be similar to a rectangle.

Thus, the cross-sectional region is a RECTANGLE.

Part B: After slicing the rectangular prism with a plane perpendicular to the base, we see that the cross-sectional region will be similar to a rectangle.

Thus, the cross-sectional region is again a RECTANGLE.

Hence, for both the parts, the cross sectional plane is a Rectangle.
