hi pls where can I get physics questions on checking the correctness of an equation using dimensional analysis
Answer:
5x + 17
Step-by-step explanation:
To answer this question, we must first simplify:
2 (x + 7) + 3 (x + 1) = 2x + 14 + 3x + 3
Then, we have to combine like terms:
2x + 14 + 3x + 3 = 5x + 17
And there is our answer, 5x + 17
Hope this helps ! :)
This expression is a good candidate for "factoring by grouping." I note that the first 2 terms and the last 2 terms share a common factor, 2x+1:
8x^3 + 4x^2 - 18x - 9
4x^2 *(2x + 1) -9 (2x+1)
This can be re-written as (2x+1)(4x2-9)
The latter factor is also easily factorable:
(2x+1)(2x-3)(2x+3) (answer)
