Step-by-step explanation:
Answer:
Zero
Step-by-step explanation:
To find the additive inverse, you merely change the sign of the number
For Example 5 {5 is the number} + (-5) {-5 is the additive inverse} = 0.
i.e. 6 + (-6) = 0
i.e (-7) + 7 = 0
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
