Hey there!


Area of square formula is:

a^2


Your equation should be:

8^2

= 8 * 8

= 8 + 8 + 8 + 8 + 8 + 8 + 8 + 8

= 16 + 16 + 16 + 16

= 32 + 32

= 64


Therefore, your answer should be:

64


Good luck on your assignment & enjoy your day!

2. Given a quadrilateral with vertices (−1, 3), (1, 5), (5, 1), and (3,−1):
zlopas [31]
<h2>Explanation:</h2>

In every rectangle, the two diagonals have the same length. If a quadrilateral's diagonals have the same length, that doesn't mean it has to be a rectangle, but if a parallelogram's diagonals have the same length, then it's definitely a rectangle.

So first of all, let's prove this is a parallelogram. The basic definition of a parallelogram is that it is a quadrilateral where both pairs of opposite sides are parallel.

So let's name the vertices as:

A(-1,3) \\ \\ B(1,5) \\ \\ C(5,1) \\ \\ D(3,-1)

First pair of opposite sides:

<u>Slope:</u>

\text{For AB}: \\ \\ m=\frac{5-3}{1-(-1)}=1 \\ \\ \\ \text{For CD}: \\ \\ m=\frac{1-(-1)}{5-3}=1 \\ \\ \\ \text{So AB and CD are parallel}

Second pair of opposite sides:

<u>Slope:</u>

\text{For BC}: \\ \\ m=\frac{1-5}{5-1}=-1 \\ \\ \\ \text{For AD}: \\ \\ m=\frac{-1-3}{3-(-1)}=-1 \\ \\ \\ \text{So BC and AD are parallel}

So in fact this is a parallelogram. The other thing we need to prove is that the diagonals measure the same. Using distance formula:

d=\sqrt{(y_{2}-y_{1})^2+(x_{2}-x_{1})^2} \\ \\ \\ Diagonal \ BD: \\ \\ d=\sqrt{(5-(-1))^2+(1-3)^2}=2\sqrt{10} \\ \\ \\ Diagonal \ AC: \\ \\ d=\sqrt{(3-1)^2+(-5-1)^2}=2\sqrt{10} \\ \\ \\

So the diagonals measure the same, therefore this is a rectangle.

Find the perimeter of the figure below. Notice that one side length is not given. Assume that all intersecting sides meet at rig

52 ft

The missing side is 5ft because 11-6 is the remaining side length.

3 1/3 (2 1/5 x−4 2/3 )−5 5/6 =0
cestrela7 [59]
3 1/3(2 1/5x-4 2/3)-5 5/6=0
Since you can't subtract 2 1/5x and 4 2/3 together you would use the next step in the order of operations which is multiplication.
(3 1/3)(2 1/5x)=(10/3)(11/5x)=110/15x
(3 1/3)(4 2/3)=(10/3)(14/3)=140/9
7 5/15x - 15 5/9
Then you would subtract 7 5/15x - 15 5/9 with 5 5/6.
7 5/15x -15 5/9 - 5 5/6=
15 5/9=15 10/18
5 5/6=5 15/18
7 5/15x - 15 10/18 - 5 15/18=
7 5/15x - 21 7/18=0
Then you would try to solve for x by isolating it on one side.
7 5/15x=21 7/18
110/15x=385/18
x=(385/18)(15/110)
x=5775/1980
x= 2 1815/1980
x= 2 363/396
x= 2 121/132
x= 2 11/12
I hope you understood!!!!
