If there are 12 shirts total and three of them were green, it would be 3 out of 12 or 3/12. Hope this helps! :)
16x² - 8x + 1 = (4x)² - 2 · 4x · 1 + 1² =(4x - 1)²
Used: (a - b)² = a² -2ab + b²
Top left and bottom right yes the rest no
Yes he is right because if u have
-6 -(-4) u would multiply the 2 signs the - and the -4 and u would get +4
then ur equation becomes -6+4 = -2
