Answer:
C) x2 + x = 306
Step-by-step explanation:
x2 + x = 306
x2 + x - 306 = 0
x2 + 18x - 17x + 18 * (-17) = 0
x ( x + 18) - 17 (x +18) =0
(x + 18) (x - 17 ) = 0
x = -18 or 17
Your answer should have been 3850 in^2
1^2/5^2 = 1/25
1/25 = 154/x
1x= 154 (25)
1x/1= 3850/1
x= 3850
Hi!
So really focus on the fact that he started at $230, and then added an amount of money which we'll call x, which made his total equal $599.
Take the parts I put in bold, and write the equation.
$230 + x = $599
Now we need to find x.
Whatever we do to the equation, we do it to both sides.
Our goal is to isolate x on one side.
Subtract 230 from both sides.
$230 - $230 + x = $599 - $230
x = $369
The answer is A. $230 + x = $599 x = $369
Hope this helps! :)

the boiling point of jet fuel is 329 degrees F. Rounded to the nearest degree, what is the temperature in degrees Celcius? Use the Formula: C = 5/9(F - 32), where C represents degrees celcius, and F represents degrees fahrenheit.
A). 165 degrees C
B). 183 degrees C
C). 201 degrees C
D). 535 degrees C
Solve:
C = 5/9(F - 32)
Simplify both sides:
C = 5/9(329 - 32) = 0
Simplify:
5/9
Equation at end of step 1:
C - (5/9 * 297) = 0
C - 165 = 0
Solve single variable:
C - 165 = 0
Add 165 to both sides:
C = 165
Therefore, Your answer would be, Letter Choice (A), (C = 165 degrees C
Hope that helps!!!!! Have a great day!!!!! : )
