Answer:

Step-by-step explanation:
The surface area of a square pyramid is the sum of the area of the squared base + 4 times the area of each triangular face, therefore:

where:
is the area of the base, where
L is the length of the base
is the area of each triangular face, where
h is the height of the face
Substituting,

For the model in this problem,
L = 12
h = 8
Therefore, the surface area here is:

Simple...
you have:

and

Now, the first one is easy just divide it...

Now....

needs to be converted...
Multiply the whole number*denominator...
4*8=32
Now add the numerator....
32+3=35
Now use the original denominator...

Now divide...

Thus, your answer.
Answer:
68
Step-by-step explanation:
The lines on both sides of the number represent absolute value. Absolute value takes any number and turns it positive no matter what.
|-68| → 68
Best of Luck!
Answer:
I know the answer
Step-by-step explanation:
x = random number then y = x + y then x = 68 So we can conclude
Answer:
-1/2
Step-by-step explanation:
the slope of the line 2x-y=5 is 2
a perpendicular line has the negative reciprocal of the slope of the other line
hopefully this helps :)
