Answer:

Step-by-step explanation:

-21-9k=-8(6k+3)

-21-9k= 48k+24

+9k          +9k

-21=57k+24

-24         -24

-45=57k

divide 57 by -45

k= -1.2

idk if that helps, sorry

<u>Here's how to solve your equation step by step:</u>

−21−9k=−8(6k+3)

<u>Step 1: Simplify both sides of the equation. </u>

−21−9k=−8(6k+3)

−21+−9k=(−8)(6k)+(−8)(3) (Distribute)

−21+−9k=−48k+−24

−9k−21=−48k−24

<u>Step 2: Add 48k to both sides. </u>

−9k−21+48k=−48k−24+48k

39k−21=−24

<u>Step 3: Add 21 to both sides. </u>

39k−21+21=−24+21

39k=−3

<u>Step 4: Divide both sides by 39. </u>

39k/39 = -3/39

Here's the answer: -1/13 or -0.08.

matrenka [14]

Let's simplify step-by-step.

3x2(x2−4x−4)+5x3+7x2+2x+11

Distribute:

=(3x2)(x2)+(3x2)(−4x)+(3x2)(−4)+5x3+7x2+2x+11

=3x4+−12x3+−12x2+5x3+7x2+2x+11

Combine Like Terms:

=3x4+−12x3+−12x2+5x3+7x2+2x+11

=(3x4)+(−12x3+5x3)+(−12x2+7x2)+(2x)+(11)

=3x4+−7x3+−5x2+2x+11

Answer:

=3x4−7x3−5x2+2x+11
