Answer:
Correct option: C -> 2
Step-by-step explanation:
The first equation is:
And the second equation is:
From the second equation, we have:
Using this value of y in the first equation, we have:
Calculating the discriminant Delta, we have:
We have , so we have two real values for x, therefore we have two solutions for this system.
Correct option: C.
(If the system of equation is actually:
We would have:
We also have , so we have two solutions for this system.
Correct option: C.)
We know that total surface area is the area of of the base + area of all the walls + area of the top
here we are working with a pyramid whose base is a square but the wall are four triangles
as triangles are connected on the top , there would be no top area ( as the top would be a point ( where all four triangles are being join )
so total area is = area of base + area of four walls ( triangles here )
