The rectangle on the right is 81 and the rectangle on the left is 24. I don't really know about the second one sorry, but I hope this helped.
What you must do in this case is to find the roots of the polynomial.
We have then:
x ^ 2 + 20x + 100 = 36
Rewriting:
x ^ 2 + 20x + 64 = 0
The values of the roots are:
x1 = -4
x2 = -16
Remember that the values of the roots are what make the polinome zero
Answer:
x1 = -4
x2 = -16
To answer this you must have 1/4 of tank which is 5 gallons then add 10 to get 15 gallons
The answer to the equation is the second option.
Speed of the jet = 460/2 miles/hour = 230 miles/hour.
In 9 hours, the jet can fly = 9×230 miles = 2070 miles.
