Answer:
feet
feet
Step-by-step explanation:
Let x be the width of a rectangle
Let l be the length of a rectangle
Let A be the area of rectangle
Given.
Length must be 12 feet longer than width
therefore
Area of rectangle
We know that area of rectangle is
---------------------(1)
put all known values in equation 1
Find roots by this formula
check both value in equation 1
for 
is satisfy the equation
So The length of rectangle 
=24.32 feet
And width is 12.32 feet
Answer:
Let
- p : this triangle has two 45 degree angles
- q : it is a right triangle
Step-by-step explanation:
Denote
- r : if this triangle has two 45 degree angles then it is a right triangle
Then, r can be written as follows
Since 
is a tautology, you get
and given that
it follows that the negation of r is
- " this triangle has two 45 degree angles and it is not a right triangle".
Then, the correct answer is C.
Step-by-step explanation:

II hope it's help......!!!!!!!!
Total = Principal * (1 + rate) ^ year
Total = 22,000 * (1.054)^1 = 23,188.00
Total = 14,000 * (1.054)^1 = 14,756.00
23,188.00 - 22,000 = 1,188.00 interest
14,756.00 - 14,000 = 756.00 interest
So the 22,000 earns (1,188.00 -756.00) = 432.00 more dollars in interest than the 14,000 dollars earns in interest.
I found the same problem but with given choices:
A.1 year
<span>B.2 years </span>
<span>C.3 years </span>
<span>D.4 years </span>
<span>E.6 years
</span>
profit = total revenue - total cost
p(x) = x³ - 4x² + 3x - 12
simply plug each choices to solve. answer must be 0.
A) p(1) = 1³ - 4(1²) + 3(1) - 12 = 1 - 4 + 3 - 12 = -12
B) p(2) = 2³ - 4(2²) + 3(2) - 12 = 8 - 16 + 3 - 12 = -17
C) p(3) = 3³ - 4(3²) + 3(3) - 12 = 27 - 36 + 9 - 12 = -12
D) p(4) = 4³ - 4(4²) + 3(4) - 12 = 64 - 64 + 12 - 12 = 0
E) p(6) = 6³ - 4(6²) + 3(6) - 12 = 216 - 144 + 18 - 12 = 78
It would take 4 years for the company to reach break-even point.
