An artist wants to frame a square painting with an area of 400 square inches. she wants to know the length of the wood trim that is needed to go around the painting. a. if x is the length of one side of the painting what equation can you set up to find the length of a side? part b. solve the equation you wrote in part a. how many solutions does the equation have? part ç.do all of the solutions that you found in part b make sense in the context of the problem? part d. what is the length of the wood trim needed to go around the painting?

The formula for the area of a square with sides of length x is A = x2 so

x2 = 400 is the equation

This equation has 2 solutions, namely x = ±√400 = +20 or -20

The negative solution does not make sense because a length cannot be less than 0.

The total length needed to go around the painting is the perimeter of the square, which is

P = 4*x = 4*20 = 80 inches

answer: i don't understand. what are the options

step-by-step explanation:

in the math equation 8 x 7 = 56, the 8 and the 7 are both factors of 56, since in this lesson we will use square tiles to figure out the factors of a whole find as many different arrays as you can, but follow one important rule: all the rows must have the i can make two rows of nine, so 2 and 9 are both factors of 18.
