Two rectangles have the same area of 24cm².The second rectangle is 4cm shorter and 1cm wider than the first.What is the length a

lukranit [14]

Answer:

First rectangle: 12 cm by 2 cm

Second rectangle: 8 cm by 3 cm

Step-by-step explanation:

You can examine factor pairs of 24 to see which pairs meet the requirements:

24 = 1×24 = 2×12 = 3×8 = 4×6

Factor pairs (2, 12) and (3, 8) have one factor that differs by 1 and another factor that differs by 4. We can use these numbers to describe the rectangles:

First rectangle: 12 cm by 2 cm

Second rectangle: 8 cm by 3 cm

Determine whether the relationship between the two quantities is proportional. Explain.

ira [324]

Answer:

Option B. No, because the graph of the line connecting the ordered pairs does no pass through the origin.

Step-by-step explanation:

we know that

A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form $k=\frac{y}{x}$ or $y=kx$

In a proportional relationship the constant of proportionality k is equal to the slope m of the line<u><em> and the line passes through the origin</em></u>

step 1

Connect the ordered pairs of the graph

The y-intercept is the point (0,20)

see the attached figure

That means, that the line not passes through the origin

therefore

The relationship between the two quantities is not proportional
