The length of the flagpole is ?

Flauer [41]

The length of the flagpole is x - 5 yards

<h3>Area of a square</h3>

The formula for calculating the area of the flagpole is expressed as:

A = L²

Given that;

A = x² - 10 + 25

Factorize

A = x² - 5x - 5x + 25

A =(x - 5) - 5(x - 5)

A = (x-5)²

Compare

L = x - 5 yards

Hence the length of the flagpole is x - 5 yards

What is a multiple of 6,9,18 between 61 and 107

Gala2k [10]

There are two possible answers: 72 and 90.

We can find the answer by looking at the largest number among the three of them: 18. The only multiples of 18 between 61 and 107 are 72 and 90. We can check that both numbers are also multiples of 6 and 9:

90 : 6 = 15
90 : 9 = 10

72 : 6 = 12
72 : 9 = 8

Meg plotted the graph below to show the relationship between the temperature of her city and the number of sweaters sold at a st

Sav [38]

The explanation about the graph is illustrated below.

<h3>How to illustrate the graph?</h3>

The graph shows 0 to 30 on the x-axis at increments of 5 and 0 to 12 on the y-axis at increments of 1. The label on the x-axis is Temperature in degrees C, and the label on the y axis is the Number of Sweaters Sold.

If you will draw lines through, (12.5,6) and (15,4), it will best represent a line of best fit, because most of the points on the same and opposite sides of line are equidistant from each other.

Equation of line passing through (12.5,6) and (15,4) A line of best is the line that passes through all or some points or only through a single point, which describes the relationship between x and y values of data set

4x + 5y = 80

5y = -4x + 80.

y = -4x/5 + 16

Slope = -4/5 and y intercept is 16.
