Length - 14 meters
Width - 7 meters
The length is twice the width - 7 times 2 = 14
There are four sides, two 14m and two 7m. 14 x 2 + 7 x 2 = 42
Answer:
y = -1/4x - 3/4
Step-by-step explanation:
First, you need to change the equation into slope intercept form. Subtract 4x from both sides to get -y= -4x + 2. Divide all parts by -1 to get y=4x-2. One thing you should know when finding the slope of a perpendicular line is that the slope is the opposite reciprocal. So, the slope is -1/4. This is your current equation: y= -1/4x + b. Plug the coordinate into the equation; it should look like this: -2= -1/4(5) + b. Multiply -1/4 by 5 to get -5/4. This is what you should have now: -2 = -5/4 + b. Add 5/4 to both sides to get -3/4 = b. Go back to your other equation and plug in -3/4 to b. This is your final equation: y = -1/4x - 3/4. Hope this helped!

Answer:
f(x)·g(x) = x³ +x² -2x -2
Step-by-step explanation:
Substitute the function definitions and simplify.
f(x)·g(x)
= (x +1)(x² -2)
= x(x² -2) +1(x² -2)
= x³ -2x +x² -2
f(x)·g(x) = x³ +x² -2x -2
Answer:
Pair 1: 10 cm and 2 cm. and the sum is 12 cm.
Pair 2: 20 cm and 4 cm. and the sum is 24 cm.
Step-by-step explanation:
Area of a rectangle is given by A = LW, where L is the length and W is the width of the rectangle.
Pair 1:
For the first rectangle W = 4 cm and A = 40 sq, cm
Then 
cm.
For the second rectangle W = 4 cm and A = 8 sq, cm
Then 
cm.
Therefore, the sum of two unknown lengths = 10 + 2 = 12 cm. (Answer)
Pair 2:
For the first rectangle W = 4 cm and A = 80 sq, cm
Then 
cm.
For the second rectangle W = 4 cm and A = 16 sq, cm
Then 
cm.
Therefore, the sum of two unknown lengths = 20 + 4 = 24 cm. (Answer)
Answer:
The three consecutive odd integers are: -1, 1, 3
Step-by-step explanation:
The three consecutive odd integers be x, x + 2, x + 4
Now according to the question
It is mentioned that
The four times the middle integer is two lower than tfhe sum of the first and third
i.e.
4(x+2) = [x + (x+4)] + 2
4x + 8 = 2x + 6
2x = -2
x = -1
Hence, The three consecutive odd integers are: -1, 1, 3
