Answer:
a) 5 x² + 3 x -10
Step-by-step explanation:
<u><em>Explanation:-</em></u>
Given polynomials
3 x² - 5 x + 1 and 8 x² - 2 x -9
Given that
3 x² - 5 x + 1 From 8 x² - 2 x -9
⇒ 8 x² - 2 x -9 - ( 3 x² - 5 x + 1 )
= 8 x² - 2 x -9 - 3 x² + 5 x - 1
= 5 x² + 3 x -10
Answer:
37
Step-by-step explanation:
Let x be the smaller number. 2x+7 is the larger number. Their difference is 22:
x+22=2x+7
x=15
So the smaller number is 15 and the larger number is 2(15)+7=37.
