You have 2 with mn so 9mn - 9mn =0
You also have 2 with m4n so -19m4n - 12m4n = -31m4n
Put it together:
-31m4n -8m2
So C

Hello there!

(6y^2 - 3y^3 + 5)(7y^5)

Use the distributive property

=(6y^2)(7y^5) + (-3y^3)(7y^5) + (5)(7y^5)

= 42y^7 - 21y^8 + 35y^5

= -21y^8 + 42y^7 + 35y^5

Which graph best represents the equation created when the slope of y = 6x is changed to 0?
luda_lava [24]

The graph with an equation y = 6x has a slope of 6. If the slope is changed to 0, the equation becomes y = 0.

<h3>What is a linear function?</h3>

A linear function is in the form:

y = mx + b

Where m is the slope (rate of change) and b is the y intercept

The graph with an equation y = 6x has a slope of 6. If the slope is changed to 0, the equation becomes y = 0.

What is the quadratic equation of least degree with zeros at 21 and -24
atroni [7]

Answer:

x^2 +3x -504

Step-by-step explanation:

Sort of do what you'd do to solve but in reverse.  You need 21 for a zero, so the binomial factor would be (x-21) since if you set that  = to zero you'd get 21.  Same for -24.  The binomial factor would be (x+24) since that would give you -24. Now that you have the two binomials, you can just multiply them and get the quadratic. :)

Can anyone help me with this ?
DanielleElmas [232]

Answer: x=35

Step-by-step explanation:

There are 720 degrees total in a hexagon. So, all of the angles should add up to that. Write out the equation

720= (4x-5)+(117)+(3x-3)+(3x+6)+(118)+(4x-3)

720=14x+230

490=14x

x=35

hope this helped you:)
