Tha area of a triangle is 5x^3+19x2+6x-18 with length x+3. using synthetic division, what is the width of the rectangle a)5x^2+4x-6 b)5x^2+34x+108+306/x+3 c)5x^3+4x^2-6x d)5x^2+34+108+306/x-3

we know that

area of rectangle = length*width

Let's assume

length of rectangle is L

width of rectangle is W

we are given

now, we can find width

now, we can plug values

we can use synthetic divison method

we get

so, option-A...........Answer

first option

a function is a relation in which an input is paired with exactly one output.

so, let's find the right answer.

in our first option, our inputs are january, february, and march. the outputs are 30, 28, and 25. each input has it's own output. this is correct!

our second option we know is incorrect, because ms. valverade has two outputs, dogs and cats. this is not a function.

our third option is incorrect as well. the yellow square has two ouputs, the square and the triangle.

lastly, in our fourth option, we see the number 7 two times with a different output. therefore, this is not a function.

remember: each input must be paired with only one output!
