Answer:

15m^3-26m^2+11m-4

Step-by-step explanation:

Find the product

(5m^2 - 2m + 1)(3m - 4)

Multiply both the parenthesis. Multiply each term inside the second parenthesis

5m^2 *3m + 5m^2*(-4) =15m^3-20m^2

-2m * 3m + (-2m)(-4)= -6m^2 +8m

1*3m +1(-4)=3m-4

Collect all the terms together

15m^3-20m^2 -6m^2 +8m+3m-4

Combine like terms

15m^3-26m^2+11m-4

What is the slope of line a? <br><br>​
emmainna [20.7K]
<h3>Answer:  -1/4  (choice C)</h3>

========================================================

Explanation:

Start at the point (0,1). This is the y intercept, which is where the graph crosses the y axis.

Then move down 1 and over to the right 4 spaces. We arrive at (4,0) which is the x intercept.

The process of "down 1, over to the right 4" can be thought of like this

rise/run = -1/4

rise = -1

run = 4

A rise of -1 indicates we go down 1 unit

The run of 4 means we move to the right 4 units

So that's why slope = rise/run = -1/4

-------------------------------------------------------

Here's another approach using the slope formula:

m = (y2-y1)/(x2-x1)

m = (0-1)/(4-0)

m = -1/4

I used the two points (0,1) and (4,0) as (x1,y1) and (x2,y2) respectively. This formula basically says "subtract the y coordinates, subtract the x coordinates in the same order, then divide the differences y over x".

-------------------------------------------------------

Side note: The line moving downhill, as we read from left to right, indicates a negative slope.

Copy the shape and fill in the missing angle. Sow the work. Thanks.
Otrada [13]

Answer:

x = -11

Step-by-step explanation:

Hello There!

create an equation

x + 51 + 60 + 80 = 180

combine like terms

51 + 60 + 80 = 191

x + 191 = 180

subtract 191 from each side

180 - 191 = -11

we're left with

x = -11
