Fernando built a robot to filter air and water efficiently. He expects the robot to filter more than 512 liters of air and water while using less than 9 Joules of energy. A represents the number of minutes the robot filters air, and W represents the number of minutes the robot filters water.

21A+14W > 21A+14W>51, A, plus, 14, W, is greater than, 512 represents the number of minutes the robot filters air and water to filter more than 512512512 liters of air and water.

0.36A+0.6W < 90.36A+0.6W<90, point, 36, A, plus, 0, point, 6, W, is less than, 9 represents the number of minutes the robot filters air and water while using less than 9 Joules of energy.

a line is an defined derm because it

a)contains an infinite number of points b) can be used to create other geometric shapes c)describes something that does not have width or depth d) is a term that does not have a formal definition. a line is an undefined term because it: contains an infinite number of points.

1. 180°. the sum of the interior angles of a triangle is 180°, for the equilateral triangle that it has three equals side is 60°+60°+60°=180°.

2. 60°. each interior angle of a equilateral triangle is 60°

3. 120°. the measure of ∠m is 120°, the sum of the angles ∠m and ∠n is equal to 180°. so, in order to find the measure of ∠m, we have ∠m+∠n=180° > ∠m=180°-∠n > ∠m=180°-60°=120°.

4. 360°. the sum of the exterior angles of an equilateral triangle is ∠m+∠r+∠x=120°+120°+120°=360°. the exterior angles of any triangle always add 360°.
