Step-by-step explanation:
To get a double of a number, we add the same number to itself. For example, double of 2 is 2 + 2 = 4. Example: Michelle has 4 marbles and Jane has double the marbles that Michelle has. ... It is easy to remember the numbers that we get by doubling one-digit numbers.
Answer:
The dimensions are 25 * 50 feet.
Step-by-step explanation:
The 3 sides of the pen will measure (2x + y) feet where x is the width and y is the length.
2x + y = 100
y = 100 - 2x
The area A = xy = x(100 - 2x) ft^2.
Finding the maximum area.
A = x(100 - 2x)
A = 100x - 2x^2 Finding the derivative:
A' = 100 - 4x
For maximum value of A this equals zero:
100 - 4x = 0
4x = 100
x = 25 ft, so this is the width.
The length is 100 - 2(25) = 50 ft.
Answer: it is b
Step-by-step explanation: just count how many lines between x and x' to the right its positive to the left its negative
X=27
You have to divide 4x=108 and you get 27!
Product means multiplication so 45 x 23 = 1035
