On a coordinate plane, a shape is plotted with vertices of (3, 1), (0, 4), (3, 7), and (6, 4). what is the area of the shape if

QveST [7]

Let
<span>A (3, 1)
B (0, 4)
C(3, 7)
D (6, 4)

step 1
find the distance AB
d=</span>√[(y2-y1)²+(x2-x1)²]------> dAB=√[(4-1)²+(0-3)²]-----> dAB=√18 cm

step 2
find the distance CD
d=√[(y2-y1)²+(x2-x1)²]------> dCD=√[(4-7)²+(6-3)²]-----> dCD=√18 cm

step 3
find the distance AD
d=√[(y2-y1)²+(x2-x1)²]------> dAD=√[(4-1)²+(6-3)²]-----> dAD=√18 cm

step 4
find the distance BC
d=√[(y2-y1)²+(x2-x1)²]------> dBC=√[(7-4)²+(3-0)²]-----> dBC=√18 cm

step 5
find slope AB and CD
m=(y2-y1)/(x2-x1)
mAB=-1
mCD=-1
AB and CD are parallel and AB=CD

step 6
find slope AD and BC
m=(y2-y1)/(x2-x1)
mAD=1
mBC=1
AD and BC are parallel and AD=BC
and
AB and AD are perpendicular
BC and CD are perpendicular

therefore
the shape is a square wit length side √18 cm

area of a square=b²
b is the length side of a square
area of a square=(√18)²------> 18 cm²

the answer is
18 cm²

What is 2 x 24/4 (24/4 is a fraction) pls help I will mark brainliest and say thanks AND rate five stars with 10 points

NISA [10]

Answer:

12

Step-by-step explanation:

Well, to make things easier, we can first note that 24/4 is equal to 6. This helps because integers are easier to work with compared to fractions. Next, multiplying 2 by 6, we get 12.

Answer:

Relative frequencies

First row

0.8125 ,0.1875 ,16

Second row

0.555 ,0.444 ,9

third row

18 , 7 , 25

Step-by-step explanation:

Given data

allowance No allowance total

Chores 13 3 16

<u>No chores 5 4 9</u>

<u>Total 18 7 25</u>

<u><em>Relative frequencies</em></u>

allowance No allowance total

Chores $\frac{13}{16} = 0.8125$ $\frac{3}{16} = 0.1875$ 16

No chores $\frac{5}{9} = 0.555$ $\frac{4}{9} = 0.444$ 9

Total <u> 18 7 25</u>
