Answer:
The length is 9in and the width is 3in
The perimeter is 24in and the area is 27in²
Step-by-step explanation:
To start we have to make 2 equations with the information that gave us the problem
l = length
w = width
w = l - 6in
l = 3w
we replace l in the first equation with (3w)
w = (3w) - 6in
w - 3w = -6in
-2w = -6in
w = -6in / (-2)
w = 3in
now we replace the value of w in the second equation
l = 3w
l = 3 (3in)
l = 9in
Now that we have the length and width we can calculate the perimeter and the area with the following formulas
p = perimeter
a = area
p = 2w + 2h
p = 2(3in) + 2(9in)
p = 6in + 18in
p = 24in
a = w * l
a = 3in * 9in
a = 27in²

All squares are rectangles. All rectangles have four sides. Logic, therefore, tells you that all squares have four sides.
It is dangerous to drive when it is snowing. It is snowing now. Logic tells you that it would be dangerous to drive right now.
All dogs have a good sense of smell. Bailey is a dog. Therefore, deductive reasoning logic tells you that Bailey has a good sense of smell.
All seniors are bad drivers. Mr. Jones is 70 years old and you won't let him drive your car because you think he is an unsafe driver.
When it rains the trees get wet. The trees are wet this morning, so it rained last night.

Answer:
-2 and 2/3
Step-by-step explanation:
(2/3) / (-1/4) is equivalent to (2/3) x (-4/1)
This equals -8/3, of which simplifies down to -2 and 2/3
Answer:
The answer to your question is 2 seconds
Step-by-step explanation:
Data
function y = -14x² + 56x
maximum height = ?
Process
1.- Find the derivative of the function
y' = -28x + 56
2.- Equal to zero the result
-28x + 56 = 0
3.- Solve for x
-28x = - 56
x = -56/-28
x = 2
4.- Conclusion
It takes to the ball 2 seconds to reach the maximum height.
