Answer:
<h2>b. (144 + 121)(144 - 121)</h2>
Step-by-step explanation:
Use a² - b² = (a + b)(a - b)
144² - 121² = (144 + 121)(144 - 121)
Answer:
△PQR and △RST are not similar.
Step-by-step explanation:
In triangle △PQR, two known interior angles are 34° and 80°. So the measure of third angle is

In triangle △RST, two known interior angles are 24° and 90°.

Two triangles are similar if their corresponding angles are same and the corresponding sides are proportional.
Since the angles of △PQR and △RST are not same, therefore we can say that the △PQR and △RST are not similar.
There are 13 almonds and 9 walnuts per bag so that’s 13+9=22 nuts per bag.
If there are x bags then the number of nuts is 22x.
Assuming y is the total number of nuts we get y=22x
