a³ + b³ = ( a + b ) ( a² - a b + b³ )
For example:
a = 1, b = 2
a³ + b³ = 1³ + 2³ = 1 + 8 = 9
( a + b ) ( a² - a b + b² ) = ( 1 + 2 ) ( 1² - 1 * 2 + 2² ) =
= 3 * 3 = 3
The formula is true.
The answer is 13, contains 1 tenth and a 3
<u>In sentence 7, the </u><u>phrase</u><u> by all accounts is best replaced by </u><u>however.</u>
Correct option is A
- The sentence that precedes 7 states something that is in contrast with it.
- Therefore 'by all accounts' in sentence should be changed to 'however' as it is generally used to present something that is different from or contrasts with the previous statement.
- Thus A is the best answer. The other options are incorrect because they do not convey the contrast that is required in the given context.
What is a phrase in grammar?
- In syntax and grammar, a phrase is a group of words which act together as a grammatical unit.

- Phrases can consist of a single word or a complete sentence.
