Answer:
the answer is 15 subtract the highest number from the lowest
The surface area would be 166.
Its radical 49 :) (by radical 7 means square root of 7)
Solution:
The difference of cubes identity is
if a and b are any two real numbers, then difference of their cubes , when taken individually:
→a³ - b³= (a-b)(a² + a b + b²)→→→Option (D) is true option.
I will show you , how this identity is valid.
Taking R H S
(a-b)(a² +b²+ab)
= a (a² +b²+ab)-b(a² +b²+ab)
= a³ + a b² +a²b -b a² -b³ -ab²
Cancelling like terms , we get
= a³ - b³
= L H S
Answer:
5/8
Step-by-step explanation:
3/4 - 1/8
We need to get a common denominator
3/4 *2/2 = 6/8
6/8 - 1/8
5/8
