Galina-37 [17]
X + y = 47
x - y = 3
--------------add
2x = 50
x = 50/2
x = 25

x + y = 47
25 + y = 47
y = 47 - 25

What is the total surface area <br> A.640<br> B.264<br> C.320<br> D.525
kykrilka [37]

Answer:

B. 264

Step-by-step explanation:

Although the figure may look odd, This is just a square pyramid on it's side.

So, to find the surface area, we need to find the area of the base and the area of the faces and add them together.

To find the area of the base:

Since the base is a square, all we have to do is multiply 8 by itself.

8 * 8 = 64

The area of the base is 12.5 in^2

To find the area of the faces:

Since the faces are triangles, we have to multiply the length by the height and divide by 2.

8 * 12.5 = 100

100/2 = 50

The area of one face is 50 in^2

To find the surface area:

Add the area of the base to the area of all 4 sides.

64 + 4(50)

64 + 200 = 264

The surface area of the pyramid is B. 264 in.^2

Need help with this so pls help!!!
Marat540 [252]
You need to simplify the expression and then you will know what the y coordinates are. I’m not good at this But you just need to solve the equation to be able to get the same coordinates by themselves. It’s sorta like geometry and algebra mixed. But first simplify the equations and then that will really help you.




Have a great day!
