Answer: C

Reasoning: There is a 40s difference between the age of 4 and 8 meaning 6 most likely would be in the center of that, which also means it’d be about half of 40. So with that we subtract 20 from 225 and thus giving us the closest length of time it should take Marsha’s 6 year old niece to run one lap, 205s.

The area of a rectangle is 2x^2 + 7x + 6. If the width is x + 2, what is its length?

Blababa [14]

Answer:

Area of a rectangle = Length × width

$2 {x}^{2} + 7x + 6 = length \times (x + 2)\\ \\ length = \frac{2 {x}^{2} + 7x + 6 }{x + 2} \\ \\ \\ = \frac{(x + 2)(2x + 3)}{x + 2} \\ \\ = 2x + 3$
