If you meant to write y=23x-4 then none of the lines are perpendicular.

I suspect you intended y=2/3x-4, then line D, y=-3/2x-4 is perpendicular.

For any line y=mx+b, you have to "invert" m to get  a perpendicular line. Inverting in this case means: flip numerator and denominator and add a minus sign.

So 2/3 becomes -3/2, hence answer D.

The 'inverted' m is called the opposite reciprocal. That's your word of the day.

Expand and simplfy (2x+1)(x+3)
Nina [5.8K]

Answer:

(2x+1)(x+3)

2x(x+3)+1(x+3)

2x2+6x+x+3

2x2+7x+3 (2x2 means two x square)

if you want you can also multiply 2x+3 by x+3

like this:

(2x+1)(x+3)

x(2x+1)+3(2x+1)

2x2+x+6x+3

2x2+7x+3 (2x2 means two x square)

They will both give you the same answer.

A table is 3 feet and 2 inches wide and a chair is 25 inches wide how much wider is the table then chair in inches
MariettaO [177]
To answer this problem, you would need to convert the values into inches.
12 inches = 1 ft

Table = 3ft 2 in = 38 inches wide
Chair = 25 inches wide

Then just subtract the two values to find how much wider the table is than the chair.

38-25=13 inches wider
