$7\sqrt3-4\sqrt6+\sqrt{48}-\sqrt{54}\\\\=7\sqrt3-4\sqrt6+\sqrt{16\cdot3}-\sqrt{9\cdot6}\\\\=7\sqrt3-4\sqrt6+\sqrt{16}\cdot\sqrt3-\sqrt9\cdot\sqrt6\\\\=7\sqrt3-4\sqrt6+4\sqrt3-3\sqrt6\\\\=\boxed{11\sqrt3-7\sqrt6}$

In the diagram below, TUVW is a rectangle. Prove triangle TZW is congruent to triangle UZV.

otez555 [7]

Answer:

By S.S.S. congruence property; ΔTZW ≅ ΔVZU

Step-by-step explanation:

Given:

TUVW is a rectangle.

To Prove : TZW ≅ UZV

Proof:

Since TUVW is a rectangle, and we know that opposite side of a rectangle is equal.

So,

$TW = UV \ \ .\ .\ .\ .\ 1$

And also TV and WU are the diagonals of the rectangle.

And the diagonals of rectangle bisects each other.

Therefore;

$TZ=ZV.........\ 2\\\\WZ=ZU..........\ 3$

Now In ΔTZW and ΔVZU

TW = UV (from 1)

TZ = ZV (from 2)

WZ = ZU (from 3)

So, by S.S.S. congruence property;

ΔTZW ≅ ΔVZU

Hence proved.

How do you do this?

tresset_1 [31]

Basically you just count how many there is of each.
So the answers would be:
Pentagon = 1
Triangle = 7
Moon = 1
Hope this helps!
