Because if each dime is 10% then I think that’s works
This is just simple. For example you have a plane of the form x=a, then you just substitute x with a, and you'll get an equation with y and z only, hence you have a 2-d trace of the intersection. It is just similar for y=b and z=c.
(1) At z=1.5, 2x^2 + 5y^2 + 1.5^2 = 4
2x^2 + 5y^2 = 1.75
Now you have an ellipse in the z=1.5 plane as your trace.
(2) At x=1, 2(1)^2 + 5y^2 + z^2 = 4
5y^2 + z^2 = 2
Now you have an ellipse in the x=1 plane as your trace.
(3) At z=0, 2x^2 + 5y^2 + (0)^2 = 4
2x^2 + 5y^2 = 4
Now you have an ellipse in the z=0 plane as your trace.
(4) At y=0, 2x^2 + 5(0)^2 + z^2 = 4
2x^2 + z^2 = 4
Now you have an ellipse in the y=0 plane as your trace.

Step-by-step explanation:
i don't know if this is correct but you have to divide 16 from 24. sorry if this is wrong im trying to do the best i can.
-1.5 + 7.5
factor out -1.5, divide 7.5 by 1.5 to factor it out of it as well (7.5 divided by -1.5) and make sure you get NEGATIVE 5.
-1.5(1 x -5)
The total surface area consists of the base area and the surface area (the area of all lateral faces). The base is a hexagon with side a=3 cm.
sq. cm.
Each lateral face is an isosceles triangle with height h=12 cm and base a=3 cm. The area of one such lateral triangle is
sq. cm.
Then the total surface area is:
sq. cm.
Answer: 119.7 sq. cm.
