When isabel began her book-selling business, she stored her inventory in her garage. now that her business has grown, she wants to rent warehouse space. lisa owns a large warehouse nearby and can rent space to isabel. the area of the warehouse is 8,100 square feet. lisa is willing to rent isabel as little as 100 square feet of the space or up to as much as the entire warehouse. her only requirement is that all spaces must be square. the total length of each row of bookshelves will be "4" /"5" of the length of the storage space.

a) let x be the area of the space that isabel rents and f(x) represent the total length of a row of bookshelves. how would you find the length of a row of bookshelves? (3 points)

b) write a function that expresses f(x). (10 points)

parallel and congruent

step-by-step explanation:

the movement of translation is linear.   these have the same translation because you are using the same rule for each point of the triangle so you will see the same slope being used to get from a point on the triangle to its image.

same slope!   you should think parallel when you see those 2 word together (well unless it's the same line but it can't be because we are coming from different points here)

congruent! because each point is being moved the same distance.

hello from mrbilldoesmath!

answer:

25x^2 + 90x + 84

discussion:

mn(x) = m(n(x)) = m( 5x + 9) =

(5x + 9)^2 + 3 =>

25x^2 + 90x + 9^2 + 3 =

25x^2 + 90x + 84                 (as 9^2 = 9*9 = 81)

which is the second choice
