Answer:
x=9
Step-by-step explanation:
90(the angle)-30=60
60-15=45
45/5=9
<u>(5(9)+15)+30=90</u>
Answer:
none
Step-by-step explanation:
General Form is the most basic form of an equation and is used as a template to form equations designed to solve a specific problem.
The equation given is "<span>(x- -1)^2 +(y-1)^2 =225.0".
The general form of this Equation would be presented as
</span>·X (+/-) Y = Z
·X^2 (+/-) Y^2 = R1

Hello.
Multiply all terms by x and cancel:
x2x+1=18x
x3+1=18x(Simplify both sides of the equation)
x3+1−18x=18x−18x(Subtract 18x from both sides)
x3−18x+1=0
(Use cubic formula)
x=−4.27015,0.055565,4.214585
Check answers. (Plug them in to make sure they work.)
x=4.214585(Works in original equation)
x=−4.27015(Works in original equation)
x=0.055565(Works in original equation)
So the answer is: 4
Have a nice day
