D - -x^2 + 3x + 7

To find this, first write out the equation:

(3x + 1) - (x^2 - 6)

Distribute the negative into x^2 and -6 so you're equation now looks like this:

3 x + 1 - x^2 + 6

Combine like terms and arrange the equation into ax^2 + bx + c to get the final answer of:

-x^2 + 3x + 7

Hope this helps!

Can someone help me pls
Wittaler [7]

Answer:

3 cm

Step-by-step explanation:

  • V_{cylinder} = 189\pi \: cm^3 (Given)

  • h_{cylinder} = 21\: cm (Given)

  • Formula for V_{cylinder} is given as:

  • V_{cylinder} = \pi r^2h

  • \implies  189\pi = \pi r^2(21)

  • \implies \frac{ 189\pi}{21\pi} = r^2

  • \implies 9 = r^2

  • \implies \pm\sqrt 9 = r

  • \implies \pm 3 = r

  • Length of radius can not negative

  • \implies r = 3 \: cm

Hope it helps you in your learning process.
