Tamara is creating a model of a rectangle. she has 26 inches of yellow ribbon to use for the border of the rectangle. she wants the length, l, to be 3 inches greater than the width, w. which system of equations could tamara use to find the dimensions of a rectangle that uses all of the ribbon?

System of equations are l = w + 3 and 2(l + w) = 26

Step-by-step explanation:

Tamara is creating a model of a rectangle.

She has yellow ribbon of length = 26 inches.

If the length of the rectangle is l and width of the rectangle is w then as per statement of the question

l = (w + 3) (1)

Now we form an equation of perimeter with given dimensions

Perimeter P = 2(length + width) ⇒ 2(l + w) = 26 (2)

Therefore system of two equations which can be solved to get the dimensions of the rectangle.

l = (w + 3) & 2(l + w) = 26

hi there! my name is zalgo and i am here to you out today. the answer is pretty simple (in a way). this equation equals to 25.2!

i hope this answer !

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

p.s.   i'll be on vacation from friday, dec 22 to jan 2, 2019. have a great new year!
