YES

  • Area of Triangle 1

Base=b

Height= h

Area 1=A1=1/2*b*h

  • Area of Triangle 2

Base=b

Height= 4h

Area of triangle 2=A2=1/2*b*4h

  • Comparing A1 and A2

A2/A1= (1/2*b*4h)/(1/2*b*h)

= (1/2*b*4h)/(1/2*b*h)

=4/1

Ratio of heights =h2/h1= 4/1

Ratio of areas =A2/A1= 4/1

They are proportional.

My thousands digit is 4
ElenaW [278]

The values In wxyz are mathematically given as

W=4

y=5

X=0

<h3>What is  the values In XYZ?</h3>
  • My one's digit and my tens digit together make up a total of seven.
  • My one digit has three more digits than my tens digit does.

Let the equation for the number be: wxyz.

  • Digits at tens place = yz
  • Diglt at ones place = z

Generally, the equation for is  mathematically given as

z+y=7 ......1

y=2+3 .......2

solving further

z+3+z-7

2z 7-3

z=2

Putting the value of z Within the second equation:

y=z+3 y=2+3

y=5

1. The digit in the thousands place of my number is 4, and

2. The digit in the hundreds place is four fewer than the digit in the thousands place.

W=4

X=w-4

x=4-4

X=0

In conclusion, the values In wxyz are

W=4

y=5

X=0

Find the perimeter of the polygon ABCD that has its vertices at A(2, –2), B(6, –2), C(6, 6), and D(2, 6).
sergiy2304 [10]

Answer:

D. 24 Units

Step-by-step explanation:

tracing the points given we get a rectangle

the perimeter of a rectangle = 2a+2b

a=length

b= width

in this case a= 8

b= 4

the perimeter of a rectangle = (2*8)+(2*4)

the perimeter of a rectangle = 16+8

the perimeter of a rectangle = 24
