Answer:

This means x equals zero

Step-by-step explanation:

For example when I have: 3x + 5 = 5, my next step would be to subtract the 5 from both sides;

I end up with 3x = 5 - 5;

Then I get 3x = 0

After this I divide the 3 to both sides to isolate the x on one side.

x = 0/3

Whenever a zero is on the numerator of a fraction it equals zero, whenever the zero is on the denominator it is undefined and this is a mathematical error.

x = 0

-15 (0) = 0

(-15)x=0

(-15) x = 0 ( divide by -15)

x = 0/-15 ( eliminate 0)

x = 0

Tom is making a rectangular garden. he decides to make the garden 30 ft long by 15 ft wide. Later, tom decides to keep the lengt

OleMash [197]

Yes. Changing the the word problem into a function, you get 30x=y.

30 = Fixed Length

x = width

y = area

No matter what width (x) you choose, the area (y) is going to be a multiple of 30 (the fixed length) because with two numbers being multiplied, if there is a fixed number that will always be the multiple and not the multiplier. For example, 10 multiplied by every number 1-10 is going to be a multiple of 10.

10x1=10, 10x2=20, 10x3=30, etc

So if Tom chooses any of these widths (x) 5, 10, or 15, y (the area) will be a multiple of 30.

30(5)=150

30(10)=300

30(15)=450

So as we double 5 to get 10, our outcome is doubled 150 to 300 and so forth. Hope this helps.
