Question

which repeated addition sentence matches the array? image of a 4-row 5-column array of yellow squares 8 + 8 + 4 = 20; 10 + 10 = 20; 5 + 5 + 5 + 5 = 20

Explanation:

Step1: Count rows and columns

The array has 4 rows, with 5 squares per row.

Step2: Write repeated addition

Add the number of squares in each row: $5 + 5 + 5 + 5 = 20$

Step3: Verify other options

$8+8+4=20$ does not match equal groups; $10+10=20$ would represent 2 rows of 10, which does not match the array.

Answer:

5 + 5 + 5 + 5 = 20
