Answer:
The roof does form a right triangle.
Step-by-step explanation:
If it is a right triangle then it will obey the Pythagoras Theorem.
Now (√186)^2 = (√93)^2 + (√93)^2
186 = 93 + 93 = 186
So it obeys the theorem and is therefore a right triangle.
Answer:
c
Step-by-step explanation:
c
We know that she spent $39, and has 3/4 of the original amount left. Our goal is to find the original amount. We can use the equation. x - 39 = 3/4x. Once we subtract x on the left hand side, we get -39 = -1/4x. Once we multiply -39 by -4, we get 146. She originally had $156.
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
