A printed page is to have a total area of 100 square inches. The top and bottom margins are to be 1 inch and the side margins to be 1.5 inches. Let l represent the total length of the page and w represent the total width of the page.

a) Write an equation, using and , to express the constraint.
b) Write an equation, using and , to express the print area of the page.
c) Write the equation of the print area in terms of only.

for a) I am getting 2l+2w=100... I don't know if this is correct.. and for b and c I don't know how to do it.. help?....thanks ahead

a. You are wrong.

Area= LxW=100 or LW=100
b. Printarea= 100-(L-2)(W-3)
for the life of me, I don't have a clue what ".., using and, " means
c. Ibid

I have posted the question again.. sorry it was "using L and w"

A printed page is to have a total area of 100 square inches. The top and bottom margins are to be 1 inch and the side margins to be 1.5 inches. Let l represent the total length of the page and w represent the total width of the page.
a) Write an equation, using l and w , to express the constraint.
b) Write an equation, using l and w, to express the print area of the page.
c) Write the equation of the print area in terms of only.

For part a), you correctly wrote the equation to express the constraint. Since there are two lengths and two widths, the equation should be: 2l + 2w = 100.

Now let's move on to part b) and c):

b) To express the print area of the page, we need to subtract the margins from the total area. The total area is given as 100 square inches, and each margin has a specific width. The top and bottom margins are 1 inch each, while the side margins are 1.5 inches each. So, the equation to express the print area is:

(Print area) = (Total area) - (Margin on top and bottom) - (Margin on the sides)

(Print area) = lw - 2(1)(w) - 2(1.5)(l)

(Print area) = lw - 2w - 3l

c) To write the equation of the print area in terms of only one variable, we can rearrange the equation from part b) to express one variable in terms of the other. Let's express w in terms of l:

lw - 2w - 3l = 0

lw - 2w = 3l

w(l - 2) = 3l

w = (3l) / (l - 2)

Therefore, the equation of the print area in terms of only w is:

(Print area) = lw - 2w - 3l = (w)(w - 2) - 3l

In summary:
a) The equation representing the constraint is 2l + 2w = 100.
b) The equation representing the print area is (Print area) = lw - 2w - 3l.
c) The equation representing the print area in terms of only w is (Print area) = (w)(w - 2) - 3l.

I hope this explanation helps! Let me know if you have any further questions.
