Place the right angle at the origin. Short leg on x-axis.
The forth corner of the square is the point on the hypotenuse where the line y = x intersects. (Draw a diagram!)
In this case the hypotenuse is y = -4x/3 + 8
x = -4x/3 + 8
7x/3 = 8
7x = 24
x = 3.428571429
Answer:
![u>\frac{3x}{7}-\frac{9x-7l}{21}](https://tex.z-dn.net/?f=u%3E%5Cfrac%7B3x%7D%7B7%7D-%5Cfrac%7B9x-7l%7D%7B21%7D)
Step-by-step explanation:
Her is your answer 3% of the sales is $180
If the sales is called 's' we can write an equation to model the statement 3% of the sales is $180:
The amount of sales is $6,000.
Your final answer is $6,000 in sales.
Area=1/2 times base times height
note:bh=base times height
a=1/2bh
b=width
h=-4+2w
h=2w-4
subsitute
a=1/2w(2w-4)
a=1/2(2s^2-4w)
a=w^2-2w
a=63
63=w^2-2w
subtract 63 from both sdies
0=w^2-2w-63
factor
find what 2 numbers multiply to get -63 and add to get -2
the numbers are -9 and 7
so
0=(w-9)(w+7)
if xy=0 then x and/or y=0
so
w-9=0
w+7=0
solve each
w-9=0
add 9 to both sdies
w=9
w+7=0
subtract 7 from both sides
w=-7
width cannot be negative so this can be discarded
width=9
subsitute
l=2w-4
l=2(9)-4
l=18-4
l=14
legnth=14 in
width/base=9 in
You would just do 13+15+26+32 which would equal 86mm
