Answer:
In physical sciences, mechanical energy is the sum of potential energy and kinetic energy. It is the macroscopic energy associated with a system. The principle of conservation of mechanical energy states that if an isolated system is subject only to conservative forces, then the mechanical energy is constant.
hope it helps ;)
Answer:
7-5n
Step-by-step explanation:
first you multiply both sides and get the equation 2n+2-7n+7 then you rearange the numbers to 2n-7n +2+7 and get -5n+7. you can change that to 7-5n.
Answer:
A
Step-by-step explanation:
Because each value of x maps onto only one value of y, it is a function.
However, because it is not the graph of a line, it is a nonlinear function.
Interior angles of any polygon with n sides always add up to 180(n-2) degrees.
<span>If a polygon is a regular polygon with n sides, and each interior angle is 179 degrees, then its interior angles will add up to 179 n. </span>
<span>In both cases, you must get the same result for what the interior angles add up to. So: </span>
<span>179n = 180(n-2). Multiply out the 180 </span>
<span>179n = 180n - 360, and subtract 180n from both sides to get </span>
<span>-n = -360, so therefore n = 360 and it would have 360 sides.</span>
