Answer:
Step-by-step explanation:
We need to solve the quadratic equation
6 = x^2 -10x
Rearranging we get,
x^2-10x-6=0
Using quadratic formula to solve the quadratic equation
a= 1, b =-10 and c=6
Putting values in the quadratic formula
So, 
Hi.
Formula for area: A = 2l + 2w, where l is the length and w is the width.
Given information:
• l = 2w - 1
• A = 21 in^2
We can plug in our values accordingly and solve for w.
A = 2l + 2w
21 = 2(2w - 1) + 2w
21 = 4w - 2 + 2w
23 = 6w - 2
23 = 6w
3.83 = w
Plug 3.83 for w into 2w - 1 to find length.
2(3.83) - 1
7.66 - 1
6.66
Finally, check your work by plugging your values into the original equation.
21 = 2(6.66) + 2(3.83)
21 = 13.32 + 7.66
21 = 20.98
Answer:
The length is approximately 6.66 inches.
Answer:
25%
Step-by-step explanation:
The increase is 4 games and 4x4=16. +4 would be adding 25 percent
Answer:
B is correct
Step-by-step explanation:
-(-x) = x, because a double negative like this equals a positive.
Therefore, you are actually saying -x+x= 0 which is true.
