Answer:
a.) 
Step-by-step explanation:

Find two numbers that add up to -6 and multiply to -40 (you will most likely need a negative and a positive because -40):
-10 and 4
Factor:

Finito.
The length of the SM parallelogram when the length of the rectangle is 15 cm and width is 8 cm is 8/5 units.
<h3>What is the area of a rectangle?</h3>
Area of a rectangle is the product of the length of the rectangle and the width of the rectangle. It can be given as,

Here, (a)is the length of the rectangle and (b) is the width of the rectangle
The length of the rectangle is 15 cm and width is 8 cm. Thus, the area of it is,

All three parts has equal area. Thus, the area of parallelogram NCMA is,

MN is the height of the parallelogram. Thus,

Thus, the length of the Sm parallelogram when the length of the rectangle is 15 cm and width is 8 cm is 8/5 units.

The slope-intercept form:

m - slope
b - y-intercept
We have the equation in standard form.
<em>subtract 2x from both sides</em>
<em>divide both sides by (-3)</em>

3 / 8 % = ( 3 / 8 ) / 100 = ( 3 / 8 ) * ( 1 / 100 ) = 3 / 800 ;
Y= $0.59(x)
y= $0.59(12)
y=?
y is the total
x is the amount of pen
so you multiply the cost of each pen with the amount of pens
$0.59 times 12
