To solve this word problem? the width of a rectangle is 7 feet less than its length. if the area of the rectangle is 170 square feet, then find the length and width.

Let's assume

length =l

width =w

we are given

the width of a rectangle is 7 feet less than its length

so, we get

now, we know that

area = length*width

now, we can plug w

we have

Area=170

now, we can factor it

now, we can solve for l

now, we can find width

so, dimensions are

...............Answer

option a.

step-by-step explanation:

if you look closely at the graph, we can notice that the function is not defined at two different points.

if you look at functions b and c, you will notice that both functions are not defined at just one point. the function b is not defined at x= -5/2 and function c is not defined at x=-5. both options are discarded, given that our function should not be defined at two fiferent points.

now, if you look closely at the graph you will notice that the function sketched is not defined at x=5 and x=-2.
