Lucia is building a square patio with a side length of n feet. she will cover the floor of the patio with tiles and put a fence around the
perimeter of the patio. the tiles cost $5 per square foot. the fencing costs $3 per foot. she will also buy additional supplies for $25. let n represent the edge length, in feet, of the patio.

what does the expression 5n^2 + 12n + 25 represent?

a. the total area of the patio.
b. the cost per foot of fencing.
c. the cost per square foot of tiles.
d. the total cost of tiling and fencing the patio.
e. the sum of the area and perimeter of the patio.

Use addition and subtraction to simplify the following polynomials. a. add polynomials: (3 – 4x + 8x^2) + (–6 + 2x – 5x^2) step 1: rewrite the polynomials without the parentheses. step 2: write the polynomial in descending order and use parentheses around like terms. step 3: add the like terms identified in step 2 to simplify the polynomial. b. subtract polynomials: (3x – 5 – 7x^2) – (–2 + 6x^2 – 5x) step 1: rewrite the polynomials without the parentheses. remember to multiply each term in the second parentheses by –1. show your work. step 2: write the polynomial in descending order and use parentheses around like terms. step 3: add the like terms identified in step 2 to simplify the polynomial.

Atriangle with all sides of equal length is a/an triangle. a. right b. scalene c. equilateral d. isosceles
