Answer:

  • 16380

Step-by-step explanation:

<u>We can see that:</u>

  • 28 + (-15) + (-13) = 0

<u>Use the following identity:</u>

  • a³ + b³ + c³ = 3abc, if a + b + c = 0

<u>Substitute the values to get:</u>

  • 28³ + (-15)³ + (-13)³ = 3*28*(-15)(-13) = 16380

Branliest offered <br> Solve equation <br> 6x+3x+8=35<br> 12w-5-3w=40
aniked [119]

6x+3x+8=35
Step 1: Simplify both sides of the equation.
6x+3x+8=35
(6x+3x)+(8)=35(Combine Like Terms)
9x+8=35
9x+8=35
Step 2: Subtract 8 from both sides.
9x+8−8=35−8
9x=27
Step 3: Divide both sides by 9.

12w−5−3w=40
Step 1: Simplify both sides of the equation.
12w−5−3w=40
12w+−5+−3w=40
(12w+−3w)+(−5)=40(Combine Like Terms)
9w+−5=40
9w−5=40
Step 2: Add 5 to both sides.
9w−5+5=40+5
9w=45
Step 3: Divide both sides by 9.

Find the value of the monomial. 5x^3 for x=0.5
Nataly [62]

Answer:

The correct answer is 166.375 <em>or</em> 166.4 when rounded to the nearest tenth.

Step-by-step explanation:

If x = 0.5, then 5x^3 = 5.5^3.

5.5^3 is the same as <em>multiplying </em>5.5 by <em>itself </em> 3 times.

5.5 x 5.5 x 5.5 = 166.375 <em>or</em> 166.4 when rounded to the nearest tenth.

Hope this helps! :D

Write equations for the vertical and horizontal lines passing through the point (0, -3).
Natasha2012 [34]

Answer:

Vertical line will be x=0, and horizontal line will be y=-3

Step-by-step explanation:

Draw a vertical line through point (0,-3). You will see it's on the y-axis. The equation of the line on y-axis is always x=0, because no matter what point you choose on the line, the x coordinate will be 0. (0,-3), (0, -2), etc.

Next draw a horizontal line through (0,-3). It's parallel to the x axis, and no matter what point on the line you choose, the y coordinate will be -3. (0,-3), (1, -3), etc
