x = °
Step-by-step explanation:
Answer:
The variable representation is x, x+2 and x+4 for this sequence.
Step-by-step explanation:
Given that:
The sum of 3 consecutive even numbers is 78.
Let,
The first even number is represented by x.
As the numbers are consecutive, thus,
First even number = x
Second even number = x+2
Third even number = x+4
Hence,
The variable representation is x, x+2 and x+4 for this sequence.
Answer: 54 square yards
Step-by-step explanation:
Given: The area of the scale model of a playground is 6 square yards.
let l be the length and w be the width of the model of playground.
then .....(1)
The scale model is enlarged by a scale factor of 3 to create the actual playground.
Then length of playground = 3l
width of playground = 3w
Then the area of the playground=
By using (1), we get
The area of the playground=
