The example I would be using is the level of a see-saw and take a point 1 /x of the way amid the middle and the left end. If you change the point vertically by f feet, the far right finish transfers vertically by f×−x feet. If you push down, f would be negative then you are multiplying two negative numbers for a positive result, this means that the other end moves up.

Daniel rides his bicycle 21km west and then 18km north. How far is he from his starting point?

This is a right triangle. To find the length of the hypotenuse a^2 + b^2 = c^2.

21^2 + 18^2 = c^2

441 + 324 = c^2

765 = c^2

Leah claims that these figures are not similar. When she compared the heights, she wrote 27. Then she compared the bases and got

Flauer [41]

Answer:

<h2>Leah is actually wrong, because those rectangles are similar.</h2>

Step-by-step explanation:

Remember that similarity is about having proportional sides and congruent angles. When we have congruent sides, then those rectangles are congruent not similar.

In this case, to find the similarity, Leah should compare bases and heights thorugh division, because the ratio between heights and the ratio between bases must be equal. So, let's divide.

$\frac{21}{6}=3.5$

$\frac{7}{2}=3.5$

As you can observe, both ratios are equal.

Therefore, those rectangles are congruent.
