Can somebody write this is quadratic form please
galina1969 [7]

To write an equation in standard form, move each term to the left side of the equation and simplify.

ax2+bx+c = 0ax2+bx+c = 0

Move all the expressions to the left side of the equation.

−17−8x2−4x+3x2 = 0-17-8x2-4x+3x2 = 0

Add −8x2-8x2 and 3x23x2.

−17−5x2−4x = 0-17-5x2-4x = 0

Reorder the polynomial.

5x2+4x+17 = 0

Step-by-step explanation:

Rasek [7]
Michelle: x
Ian: 5x
Joe: 7x
Michelle + Ian + Joe = 208 berries
x + 5x + 7x = 208
Combine like terms: 13x = 208
Divide both sides by 13: x = 16
Joe = 7x = 7*16=112
Joe picked 112 berries

What is 3 divided by 2/3 x 3? <br><br> please show work!
IgorC [24]

<u>Answer:</u>

<em>The correct answer is 1 1/2</em>

<u>Step-by-step explanation:</u>

<em>First, We need to find out the sum of 2/3  x 3, change 3 into a fraction if you want</em>

<em>3x2=6 and 1x3 is 3, So 2/3 x 3 is 6/3 or 2</em>

<em>Next, divide 3 by 2, change to fractions if needed</em>

<em>Remember keep, change and flip, flip 2/3 to 1/2</em>

<em>Then, you multiply 3/1 and 1/2 3x1=3 1x2=2</em>

<em>Finally divide 3 by 2. 3  ÷ 2 is 1 1/2</em>

<em>I hope this helped!</em>
