Hello!
You can only add values that have the same terms
4k^4 + 5k^4 = 9k^4
-3k + k = -2k
-8 + 2 = -6
The answer is 9k^4 - 2k - 6
Hope this helps!
(-7)*(2/5 + (-3/7))
= -14/5 + 3
=1/5
your marks 9 my marks 5
Step-by-step explanation:
1/2 of 14 = 7
7 + 2 = 9
14 - 9 = 5
so your marks are 9 and mine are 5
Hope this helped ..
The simplest form of the given expression can be written as -5x² + 25x - 3.
The given parameters:
2x(x + 6) - 7x² + (13x - 3)
The given expression can be simplified as follows;
2x(x + 6) - 7x² + (13x - 3)
= 2x² + 12x - 7x² + 13x - 3
<em>collect similar terms together</em>
= (2x² - 7x²) + (12x + 13x) - 3
= -5x² + 25x - 3
Thus, the simplest form of the given expression can be written as -5x² + 25x - 3.
