The Perimeter of the rectangle below is 94 units find the length of side peek you write your answer without variables
ivolga24 [154]

Answer:

DC = 21 ; BC = 26

Step-by-step explanation:

The perimeter of a rectangle is given by :

P = 2(length + width)

2x + 3

3x - 1

Perimeter, P = 94

Hence,

94 = 2(2x +3 + (3x - 1))

94 = 2(2x + 3 + 3x - 1)

94 = 2(5x + 2)

94 = 10x + 4

94 - 4 = 10x

90 = 10x

x = 90 /10

x = 9

DC = 2x + 3 = 2(9) + 3 = 18 + 3 = 21

BC = 3x - 1 = 3(9) - 1 = 27 - 1 = 26

Raju covers a certain distance in 1 hour and sham covers the same distance in 2 hours , who travels in a higher speed?
dimulka [17.4K]

Answer: Raju travels at a higher speed.

Step-by-step explanation:

Speed =\dfrac{Distance}{Time}

Speed inversely proportional to time.

As time taken to cover a particular distance decreases the speed will increase.

Raju covers a certain distance in 1 hour.

Sham covers the same distance in 2 hours.

1< 2

Thus Raju travels at a higher speed.

The voting trends for 163 countries were studied. Malta was rated number 1, but was left off of Table 2-2 which is a random samp
Crazy boy [7]
I think the possible way that the percentage vote of a country is different to the next random sampling to the other data table is its population in each country. In the first table i think Malta has the edge to this table data and place in number 1 but to the other data table the country was left of.
