U+(v-t)
that’s the answer!
Answer:
14
Step-by-step explanation:
To find TV you must add the length of TU (6) by the length of UV (4x) to find x to find the length of TV(7x).
6<u>+4x</u>=7x
Do inverse operations to solve for x.
6=<u>3x</u>
x=2
Now that we know x is 2, we must substitute 2 in for the x in the equation for TV (7x).
7 × 2 = 14
TU = 14
You would reorder the terms to 2x = 22 and divide 22 by 2 which would be 11

Step-by-step explanation:
the total surface area of such a pyramid is the sum of 5 sides :
1 bottom square (8×8)
4 side triangles (baseline 8, height 11.7)
the inner height of the pyramid we don't need, as the slant height is already given, and that is the height of the triangles of the wall of the pyramid.
the area of a triangle is
baseline × height / 2
if the slant height was unknown, we would have used the inner pyramid height and the side lengths to calculate the slant height.
so, we get a areas
bottom square = 8×8 = 64 in²
a side wall triangle = 8×11.7/2 = 4×11.7 = 46.8 in²
all 4 side triangles = 4×46.8 = 187.2 in²
so, the total surface area is
64 + 187.2 = 251.2 in²
