Answer:
-2150000
Step-by-step explanation:
I hope this right cause my head hurt doing that
You need to get L by itself. Keep in mind with equality problems that what you do to one side, you must do to the other.
Let me break it down for you.
P=2L+2W, -2w from both sides.
P-2W=2L, now divide the other side by 2.
1/2P-W=L
Answer:
Well we know that it's a linear because it has a exponent so what we do to answer this question
Step-by-step explanation:

x2+ 12x +20 =0
a=1
b=12
c=20
_______
X= -12+v 12 2 -4 • 1 • 20

a.
b.
The metal obey this law for values of strain until 0.05, where we have a linear relationship (each increase of 0.01 in the strain causes an increase of 100 in the stress). After this point, we don't have a linear relationship anymore.
c. Since an increase of 0.01 in the strain causes an increase of 100 in the stress, the slope is:
Now, calculating the coefficient b (y-intercept), we have:
So the equation is:
d.
The maximum value of stress is 560, and occurs at strain = 0.07.
