Stefanie swam 1/3 further in the morning.
4/5 - 7/15
12/15 - 7/15 = 5/15
5/15 = 1/3
D.
(-4v*3v) + (-4v*-5) + (3v*7) + (7*-5)
-12v^2 + 20v + 21v -35
-12v^2 + 41v -35
Answer:
f(x) = 2x³ - 6x² - 48x + 24
relative minimum: (4,-136)
relative maximum: (-2,80)
answer is the second option
Answer:
A is the correct answer.
Step-by-step explanation:

Thus, option A is the correct answer.
There are a few ways to go about doing this, but the easiest is portably to break it up into three shapes: two identical triangles, and a rectangle. The area of one triangle is:
1/2 (10x8) = 40, so the area of two triangles is 80.
The area of the square is 20 x 8, which is 160.
The total area is the sum of the two:
80 + 160 = 240, and this is your total area.
