1. The coefficient of 2 is 2. Therefore, the answer is 2 for a. 1 is the coefficient of -x after we add it to the left side. Therefore, b is 1. C is 5, as it is the only whole number.

This means that the answer is a = 2, b =1, c =5.

2. You can simply cancel out both of the 3s by dividing, which leaves us with  1+9.

3.  The answer is c.

I hope this helped!

Answer:

Step-by-step explanation:

1. The coefficient of 2x^{2} is 2. Therefore, the answer is 2 for a. 1 is the coefficient of -x after we add it to the left side. Therefore, b is 1. C is 5, as it is the only whole number.

This means that the answer is a = 2, b =1, c =5.

2. You can simply cancel out both 3s by dividing, which leaves us with  1±9\sqrt{5}.

3.  The answer is c. Unfortunately, I can't explain that, it's just a well known formula.

I hope this helped!

HELP ME PLEASE I NEED HELP​
Olin [163]

Step-by-step explanation:

You should prolly subtract 2 from both sides first.

So you get, -|2/5x + 3| > -1 2/5

  • Add three to both sides
  • -|2/5x| = -1 2/5
  • Do -1 and 2/5 divided by 2/5 to get -3.5, x > -3.5

One of the answers is x > -3.5 but you need to switch the sign to less than and make the other side the opposite.

-( \frac{2}{5}x + 3 ) < 1 \frac{2}{5}

You see that, switched the sign and made whats on the right side opposite. So now solve for x again but with this new equation. Also, the parentheses are absolute value signs

Subtract 3 from both sides

-|2/5x| < -1 and 3/5

Divide 2/5 from each side to get x < -4

I hope I'm correct, my bad if I'm wrong

CAN YALL PLEASE WORK IT OUTTT <br><br> $18.79 + $2.11 + ‐$1.92 + $17.28
Dmitry [639]

Answer:

40.1

Step-by-step explanation:

Because the order of operations (Bodmas or Pedmas) tells you to add from left to right. So you would do 18.79 + 2.11 = 20.9, then you would do 20.90 + 1.92 (Add 0 at the end of 20.9) = 22.81. Then you will add 22.81 + 17.28 = 40.1. So your answer is 40.1. Hope this helps!
