Answer:
The answer to your question is: Total surplus = - x² + 400 x + 10,000
Step-by-step explanation:
Data
Alphaville - 2x² + 500 x
Betaville x² - 100 x + 10,000
Surplus of both towns = ?
Process
Add the surplus of both towns
Total surplus = Alphaville surplus + Betaville surplus
Total surplus = - 2x² + 500 x + x² - 100 x + 10,000
Total surplus = - x² + 400 x + 10,000

Answer:
m<PQR = 80°
Step-by-step explanation:
<u>Points to remember</u>
Sum angles in a linear pair is 180
<u>To find the value of x</u>
It is given that, angle PQR and angle RQS are linear pairs, and
m< PQR =5x+5 and m<RQS =11x-65
m<PQR + m<RQS = 180
5x + 5 + 11x - 65 = 180
16x -60 = 180
16x = 180 + 60
16x = 240
x = 15
<u>To find the value of angle PQR</u>
m<PQR = 5x + 5
= 5*15 + 5
= 75 + 5 = 80
Therefore m<PQR = 80°
It's a right triangle
if there is one 90°
50.24 because you have to remember Pi times radius squared is area of a circle
