You would pay $16.4. you would do: 20 times .18 which equals $3.6 off. 20-3.6= $16.4.
So your equation would be x+3 times x+2 = 30
When you factor this out, you get x^2 + 5x + 6 = 30
Then you have to move the 30 over so you can set it equal to zero, so subtract 30 from both sides of the equal sign.
You now have X^2 + 5x -24 =0
Here you'd try to refactor, but unfortunately that doesn't work in this equation so you have to use the quadratic formula.
Look up the formula if you don't know it, it would be more confusing if I tried to type it out. Just keep in mind that for this equation, a=1 b=5 and c= -24.
Step-by-step explanation:
Make sure first this question is correct or notCause ik about 5y and 2y and what about 3x ?
Answer:
x=2
