Use the GCF to factor this expression. 40x + 24y – 56 1(40x + 24y – 56) 2(20x + 12y – 28) 4(10x + 6y – 14) 8(5x + 3y – 7)

Without any equipment, you can see stars that are 2{,}800{,}0002,800,0002, comma, 800, comma, 000 light-years away. by looking through a small telescope, you can see stars that are 3{,}112{,}000{,}0003,112,000,0003, comma, 112, comma, 000, comma, 000 light-years away. approximately how many times as far can you see using a small telescope as without any equipment?
