A rectangle is shown. All angles are right angles. The length of one side is 2 x and the length of another side is 3 x + 3. The
Doss [256]

Answer:

Step-by-step explanation:

Alright, lets get started.

Please refer the diagram I have attached.

The perimeter of the rectangle will be : 2\times(\ length+width)

The perimeter will be : 2 \times(2x+3x+3)

The perimeter will be : 10x+6

As per given question, the perimeter is given as 146 unit.

So,

10x+6=146

Subtracting 6 on both sides

10x=140

x=14

Plugging the value x in sides, the sides will be 2 \times 14=28 and

3 \times 14+3=45

Hence the length of the longer side is 45 units.   :   Answer

Hope it will help :)

If xy=0, what must be true about either x or y
evablogger [386]

Answer:

either x or y must equal 0​

Step-by-step explanation:

ts given that xy = 0

Remember that product of two numbers can be zero only if:

Both of them are zero or Either of them is zero as zero multiplied to any non-zero number will always be equal to zero. This is known as Zero Product Property.

So, if the product of x and y is equal to 0 there are two possibilities:

Both x and y are equal to 0

Either x or y must be equal to 0

Note that the condition both x and y are equal to zero is not a must condition, because even if one of them is equal to zero, the entire expression will be equal to zero.

Hence, the condition which has to be true in all cases for xy = 0 is:

either x or y must equal 0​

Neither one will ever hit the axis I think? if its x=3.5 then its horizontal but its above the x axis. Same with the second one. its vertical and will never hit the y axis. Not sure how to write that into those boxes but I think there isn't an intercept.
