Answer:
D= 37
C= 53
x+x-16=90
+16 +16
2x=106
/2 /2
x=53
The answer is (1) x=-2. The property of the equation like y=ax2+bx+c is that the axis of symmetry of the graph is x=-b/2a. So for this question, the axis is x=-4/2=-2.
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 )

Answer:
I believe it is $65
Step-by-step explanation:
$55/5.5
Divide the $55 by 5.5 and you get $10, then add it to your original $55, that makes $65, right?
