Answer:
a) SAS
b) Volume of DEF is 4 times the Volume of ABC
Step-by-step explanation:
a) since they have one same/congruent angle (angle B and angle E) and other two sides are in the same ratio, they are similar by SAS similarity theorem.
40/20 = 30/15 = 2
Therefore Δ ABC is similar to Δ DEF
b) Volume of a prism
= base area × height
Let height be 'h cm'
With Base ABC:
Volume = ½×20×15×h = 150h cm³
With Base DEF:
Volume = ½×40×30×h = 600h cm³
600h/150h = 4
Prism with base DEF has a greater volume; it's 4 times of the volume of the prism with base ABC
Answer:
B
Step-by-step explanation:
Given:
The polynomial is
To find:
Based on its number of terms name for the given polynomial.
Solution:
We have,
Here, number of terms is 3.
Any polynomial with three terms is known as trinomial.
Therefore, based on its number of terms the given polynomial is called a trinomial.
