Question:
l = 5 + w
perimeter = 22
width?
Solution:
Perimeter = 22
2(l + w) = 22
2(5+w+w) = 22
2 (5 + 2w) = 22
5 + 2w = 11
2w = 6
w = 3
The width is 3
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.
