In football, the team that has the ball has four chances to gain at least ten yards. If they don’t gain at least ten yards, the other team gets the ball. Positive numbers represent a gain and negative numbers represent a loss. Select all of the sequences of four plays that result in the team getting to keep the ball. (Lesson 5-14) Multiple select question. A) 8, -3, 4, 21 B) 30, -7, -8, -12 C) 2, 16, -5, -3 D) 5, -2, 20, -1 E) 20, -3, -13, 2

check the picture below.

well, the angle at the vertex d is clearly not a right-angle, let's check for the one at the vertex f which does look like,   however if it's indeed, that means ef is perpendicular to df, in which case their slopes will be negative reciprocal of each other.

so the negative reciprocal of the slope of ef is 1, however the slope of df is not 1, is 1/2, so nope, they're not perpendicular lines.

a. -0.3 > -0.33

5/12, or 5: 12
