Answer:

s =  -\frac{3}{2}  or -1.5

Step-by-step explanation:

4s² + 12s = -9

→ Add 9 to both sides

4s² + 12s + 9 = 0

→ Find factors that times to 9 and add to 12

( 2s + 3 ) ( 2s + 3 ) = 0

→ Solve

s =  -\frac{3}{2}  or 0.15

\\ \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}

Any clue on this one please help
barxatty [35]

Yes, because they both have the same slope, and a translation doesn't have an affect of the slope. Both slopes are 1, because they are going +1x and +1y, or 1/1 which = 1.
