Rosa is sewing a ribbon around the sides of a square blanket. each side of the blanket is 72 inches long. how many inches of ribbon will risa need?

Hello! The answer to your question would be as followed:

She needs 72 inches per sides of the blanket.

A blanket has four sides so you have to multiply 72 by 4.

72 x 4 =

288 inches

288 inches

Step-by-step explanation:

Given : Rosa is sewing a ribbon around the sides of a square blanket.

Each side of the blanket is 72 inches long.

Then, the length of the required ribbon = Perimeter of the square blanket.     (1)

Perimeter of square =4 (Side)

Then, Perimeter of the square blanket= 4(72)=288 inches      (2)

From (1) and (2),

The length of the required ribbon = 288 inches

option c) graph of line going through 1, 4 and 3, 10

step-by-step explanation:

let y equal to margo's coin collection

let x equal to number of years

at the begining x=0, y=1 → point=(x,y)→point=(0,1)

she adds 3 coins per year, then y=1+3x

at x=1, y=1+3(1)=1+3→y=4→point=(x,y)→point=(1,4)

at x=3, y=1+3(3)=1+9→y=10→point=(x,y)→point=(3,10)

the graph of line going through (1, 4) and (3, 10), then the option c is the correct.
