First, use front end rounding to estimate each answer. Then find the exact answer.A certain town receives 303 days of rain a year. On average, how many days a year does it not rain?
A. estimate: 370 - 300 = 70 days; exact: 365 - 303 = 62 days B. estimate: 400 - 303 = 97 days; exact: 365 - 303 = 62 days C. estimate: 400 - 300 = 100 days; exact: 365 - 303 = 62 days D. estimate: 365 - 300 = 65 days; exact: 365 - 303 = 62 days
The middle term of the trinomial has been rewritten. Now factor by grouping.y2 + 6y + 4y + 24
A. (y + 6)(y + 4) B. (y + 6)(y - 4) C. y(y + 34) D. (y - 6)(y - 4)
Write the equation in standard form.y = (x - 6)2
A. y = x2 - 6x + 36 B. y = x2 - 12x + 36 C. y = x - 36 D. y = x2 - 36
