Answer:
i dont know, ive never learned this haha. i sat here for at least 45-50 minutes trying to figure it out. sorry :/
Step-by-step explanation:
5(8x - 10) - 10x + 25(8x - 10) - 10x + 2
= (40x - 50) - 10x + (200x - 250) - 10x + 2
= 40x - 50 - 10x + 200x - 250 - 10x + 2
= (grouping like terms together)
= 40x - 10x + 200x - 10x - 50 - 250 + 2
= 220x - 298
