Answer: There are <u>4</u> teams in the league
Step-by-step explanation:
(1) Add 14 four times: 14+14+14+14 = 56
(2) Multiply 14 four times: 14 x 4 = 56
(3) Combine both of these numbers into the <em>t </em>factor: 14t = 56
(4) Divide both sides by 14 and simplify: (14t / 14) = 56/14 | t = <u>4</u> (simplified)

To solve this, you simply need to calculate the length of each side of the triangle with the vertexes of A(3,4), B(-5,-2), and C(5,-2). The length of each side is simply calculated using the pythagoras theorem. Note that it doesn't matter what order you do the subtraction. The absolute value will be the same and if it happens to be negative, not a problem since it will become positive once you square the values.
So the length of side AB is
sqrt((3-(-5))^2 + (4-(-2))^2) = sqrt(8^2 + 6^2) = sqrt(64 + 36) = sqrt(100) = 10.
The length of side BC is
sqrt((-5 - 5)^2 + (-2 - (-2))^2) = sqrt(-10^2 + 0^2) = sqrt(100+0) = sqrt(100) = 10.
And finally, the length of side AC is
sqrt((3-5)^2 + (4-(-2))^2) = sqrt(-2^2 + 6^2) = sqrt(4+36) = sqrt(40)
= 2 * sqrt(10)
Finally, add all the lengths together.

No because the box has a fixed weight as the several books weighing said pounds would most likely to be use as the x in this equation.
$425 - $25 = $400
$400/ 2 (the two people)= $200
Seiji made $225 because it said he made $25 more
and Gavin made $200
