Answer 1
Answer: Functions can only have 1 value of 'x'.

Option A is not a function because it has two -5's

Option B is not a function because it has two -2's.

Option C is a function.

The perimeter of a rectangle is 34 units. Its width is 6.5 units

Answers

and what else is there do you want the length? and the width?.
okay so a rectangle right? one side is 6.5, since one side should be perpendicular to another, that's 13 units off. So 34-13=?21, so 21/2 is 10.5.
So the length is 10.5

Water weighs about 62 pounds per cubic foot. What is the weight of the water in the pond in problem 4?( Problem 4- The pomerantz family have a small rectangular pond in their flower garden. The pond is 6 feet long and 4 feet wide.If the water pond is 2 feet deep, What is the volume of the water) SHOW WORK PLEASE!!

Answers

The volume of the pond is 48 cubic feet. Then the weight of the water in the pond will be 2,976 pounds.

What is the volume of the rectangular prism?

Let the prism with a length of L, a width of W, and a height of H. Then the volume of the prism is given as

V = L x W x H

Water weighs about 62 pounds per cubic foot. The pond is 6 feet long and 4 feet wide. If the water pond is 2 feet deep. Then the volume of the water pond is calculated as,

V = L x W x H

V = 6 x 2 x 4

V = 48 cubic feet

Then the weight of the water in the pond will be given as,

W = 62 x 48

W = 2,976 pounds

The volume of the pond is 48 cubic feet. Then the weight of the water in the pond will be 2,976 pounds.

More about the volume of the rectangular prism link is given below.

CAN ANYONE PLEASE HELP WITH MATH?The rectangle has an area of 4(x+3) square units.
A- If the dimensions of the rectangle are doubled, what is the area of the new rectangle in terms of x? Show your work.


B- Will the ratio of the area of the original rectangle to the area of the larger rectangle be the same for any positive value of x? Explain.

Answers

A)
If it has an area of 4(x+3) we can think that one side has a length of 4, and the other has a length of (x+3).

So, if the dimensions were doubled, 4 x 2 = 8. And 2(x+3) = 2x+6.

The new area would be:

8(2x+6) = 16x+48.

B) 
The ratio will be the same. For example lets plug in some points:

x=0
4(0+3) = 4(3) = 12

And 
16(0)+48 = 0+48 = 48

So the ratio is 48/12 = 4

Lets plug in another point.

x=2
4(2+3)= 4(5) = 20

And
x=2
16(2)+48 = 32 + 48 = 80

80/20 = 4

So the ratio is the same :)
A- a_(1) = length , b_(2)=width, A_(1)= Area;
a_(2)=na_(1) , b_(2)=nb_(1) ==> A_(2)= 2^(n) A_(1)
if we double the dimensions of the rectangle, the area will be fourfold:
A_(2) = 2^2[4(x+3)]=16x+48

B- yes, it will always be the same because:
(A_(2))/(A_(1)) = (4(4(x+3)))/(4(x+3)) =4

What goes into 18 and 42 for equivalent fractions

Answers

6 is a number that goes into both 18 and 42 if that helps, you can divide 18 by 6 and you get 3, then 42 by 6 and get 7, and that is how you simplify that part. I hope that helped :)
