Answer:
<h2><em><u>-2x</u></em><em><u> </u></em><em><u>+</u></em><em><u> </u></em><em><u>7y</u></em></h2>
Step-by-step explanation:
<em><u>Given</u></em><em><u>, </u></em>
5x– 4у + 3y+8y – 7х
<em>[Bringing like terms together]</em>
= 5x - 7x - 4y + 3y + 8y
<em>[</em><em>Adding</em><em> </em><em>and</em><em> </em><em>subtracting</em><em> </em><em>the</em><em> </em><em>like</em><em> </em><em>terms</em><em>]</em>
= <em><u>- 2x + 7y (Ans)</u></em>
Step-by-step explanation:
As ANC are collinear,
AB+BC=AC
so,
18+BC = 41
BC = 41-18
BC = 23 is the answer.
To find the total measure of the angles in a polygon, the formula is 180(n-2) n being the number of sides in the polygon.
So the correct answer is B) 180(14-2)
Answer:
The answer is below
Step-by-step explanation:
a) The integral 
means the total change in level of water in inches from 1 am to 10 am. That is the water level change measured in inches between 1 am and 10 am
b) 7 pm is represented as t = 19 hours, while midnight is represented as t = 24 hours, hence the water level change between 7 pm and midnight is:
c) Using casio calculator to evaluate the integral gives:
= 2.54 inches
D) The total daily change in water level = 
= 0.35 inches
