Find two consecutive numbers whose squares differ by 45
Wittaler [7]

Answer:

The 2 numbers are 22 and 23

Step-by-step explanation:

let the two numbers be x and x+1

according to the question:

(x+1)^2 - x^2 = 45

x^2+1+2x - x^2 = 45

2x + 1 = 45

2x= 44

x = 22

the other number is x+1 = 22+1 = 23

therefore, the two consecutive numbers are 22 and 23

A tile pattern has five tiles in Figure 0 and adds seven tiles in each new figure. Write a linear equation that represents this
Olenka [21]

The linear equation that represents the <u>number of tiles in figure x</u> is given by:

y = 7x + 5

---------------------

A linear equation has the format:

y = mx + b

In which:

  • m is the slope, that is, the rate of change.
  • b is the y-intercept, that is, the value of y when x = 0.

---------------------

  • Figure 0 has 5 tiles, that is, when x = 0, y = 5, thus b = 5
  • Seven new tiles in each figure, that is, a rate of change of 7, thus m = 7

The number of tiles in figure x is given by:

y = 7x + 5
