Answer:
The solution for this equation is n= -4. I didn't see any other equations listed so i can not help compare each equation but hopefully this helps you :)
Step-by-step explanation:
-5n+31= -14n-5
**add 14
9n+31= -5
** subtract 31
9n= -36
** divide 9
n= -36/9
n= -4
If 2/3=0.666666667
If 5/7= 0.71428571428
Times those two numbers and equals to= 0.47619047642
Hello from MrBillDoesMath!
Answer:
sqrt(105)
(which is approximately 10.25 centimeters
)
Discussion:
Call the unknown leg"a". From the Pythagorean theorem
8^2 + a^2 = 13^2 => subtract 8^2 = 64 from both sides
a^2 = 13^2 - 64 => as 13^2 = 169
a^2 = 169 - 64 = 105 => take the square root of both sides
a = sqrt(105) which is approximately 10.25 centimeters
Thank you,

Its because when you fold the paper its makes it half so thats why it would be like that.
The correct answer is b, x < -3.
Since the area shaded is left of x = -3, x has to be less than -3.
