Check the obtained values of 4s²+12s=-9

marta [7]

$\\ \bull\tt\looparrowright 4s^2+12s=-9$

$\\ \bull\tt\looparrowright 4s^2+12s+9=0$

$\\ \bull\tt\looparrowright 4s^2+6s+6s+9=0$

$\\ \bull\tt\looparrowright 2s(2s+6)+3(2s+3)=0$

$\\ \bull\tt\looparrowright (2s+6)(2s+3)=3$

$\\ \bull\tt\looparrowright s=-2\:or\:s=\dfrac{-3}{2}$

One number exceeds the other by 9 and their sum is 81. Find the<br> numbers.

julsineya [31]

Answer:

36, 45

Step-by-step explanation:

Using equations you get $x + x+9=81$ because one number is 9 more than the other and the sum is 81. Simplifying you get, $2x = 72$ . Divide both sides by 2 to get $x=36$ . Remember this is only x so to get the other number you have to add 9 to 36 to get 45 as the other number.
