Does anyone know of a rectangular has an area of 30square meters and a perimeter of34 Meter. What are the dimensions of a rectangle

Answers

Answer 1
Answer: Yes...
to find the answer, first find all of the factors of 30
then, find the perimeter if those two were the two lengths of the rectangle...
until you find a pair of side lengths that make the perimeter = 34

To begin...
1 and 30 --> A=30; P=62          X

And so on

Hope this helps!

Yolanda owns 4 rabbits. She expects the number of rabbits to double every year.Write an equation to model this situation.

Answers

R=Number of rabbits

y=Years that have passed by { y ≥ 0 }

R=f(y) --> R is a function of y.
---------------------------------------------

Note that when:

y=0, R=4 ---> Point: (0, 4)

y=1, R=8 ---> Point (1, 8)

y=2, R=16 ---> Point (2, 16)

y=3, R=32 ---> Point (3, 32)

y=4, R=64 ---> Point (4, 64)

--------------------------------------------

So the equation you want is going to form a curved graph.

That equation is:

R={ 2 }^( y+2 )

*You can test out this function on any decent graphing software.
This is an exponential function.

At year x, the number of rabbits would be as follows:

y=4e ^((x*(In2)))

Where x is the number of years

Bradley solved the following equation: 4(5x – 6) = 2(8x + 10) Step Work Justification 1 20x – 24 = 16x + 20 2 4x – 24 = 20 3 4x = 44 4 x = 11 Which of the following has all correct justifications Bradley used to solve this equation? 1. Associative property of addition. 2. Subtraction property of equality. 3. Addition property of equality. 4. Multiplicative inverse. 1. Associative property of addition. 2. Subtraction property of equality. 3. Addition property of equality. 4. Division property of equality. 1. Distributive property. 2. Subtraction property of equality. 3. Addition property of equality. 4. Multiplicative property of equality. 1. Distributive property. 2. Subtraction property of equality. 3. Addition property of equality. 4. Division property of equality.

Answers

Solution:

The equation solved by Bradley is

→4(5x – 6) = 2(8x + 10)

Step Work  

1. 20 x – 24 = 16 x + 20    → [ Distributive property]

Taking variable on one side of equation

2 . 4 x – 24 = 20  → [Subtraction property of equality.]

Taking constant on one side of equation

3 . 4 x = 44 →[Addition property of equality.]

Dividing both sides by 4

4 . x = 11          → [Division property of equality.]

Out of all the four options given ,Fourth option [ 1. Distributive property. 2. Subtraction property of equality. 3. Addition property of equality. 4. Division property of equality ], completely satisfies the work done  in equation.
