Expand the binomial first, then distribute the 4:

4 (<em>x</em> + 1)² = 4 (<em>x</em> ² + 2<em>x</em> + 1)

… = 4•<em>x</em> ² + 4•2<em>x</em> + 4•1

… = 4<em>x</em> ² + 8<em>x</em> + 4

1/8 of the boys at a high school tried out for the football team, 1/6 tried out for the baseball team, and 1/ 12 tried out for t
Xelga [282]

Answer:

2/3

Step-by-step explanation:

This problem is an overlap problem. First we have that 1/8 total tried out for football team, 1/6 total tried out for baseball team and 1/12 of the students that tried out for both football and baseball team.

So if we want to find those who just tried football, we perform the following operation:

1/8 - 1/12 = 1/24.

So we know that 1/24 tried out just football.

If we want to find all those who tried out just for baseball, we perform the following operation:

1/6 - 1/12 = 1/12

So we know that 2/24 (1/12 multiplied by two) tried  for both football and baseball and 3/24 tried out for football, it means that 2/3 of the boys who tried football also tried baseball.

Find the slope of the line passing through each of the following pairs of points. (0, 7), (0, −8)
neonofarm [45]
First off,we need to understand the formula of slope:
\frac{y1 - y2}{x1 - x2}
Where y is the y coordinate and x is the x coordinate.

In this case:
\frac{7 - ( - 8)}{0 - 0}   \\ = 7  + 8  \\ = 15

Therefore the answer is 15.

Hope it helps!
