Answer:
D
Step-by-step explanation:
The quadratic formula:
where a is the coefficient of 
, b being the coefficient of 
and c being the constant.
Plug in the values:
Since 
The answer is:
3x+15^2+10= -2
3x+225+10= -2
3x+235= -2
Divide both sides by 3
x+235=0.67
Subtract 235 from both sides
x= -234.33
Sorry, in advance, if I did it wrong.
A is the correct answer. Both diagonals would be the same length as it is a rectangle and when you substitute 7 for X in the equations, the answer is 26 for both.
The value of x in (1/6)/2 = x/3 is 1
<h3>How to solve for x?</h3>
The equation is given as
(1/6)/2 = x/3
Cross multiply in the above equation
x * 2 = (1/6) * 3
This gives
x * 2 = 1/2
Cross multiply
x = 2 * 1/2
This gives
x = 1
Hence, the value of x in (1/6)/2 = x/3 is 1

Answer: -4
Step-by-step explanation:
p(x)=x^3+3x^2+ax-12
x+3 is factors means it divide completely so x=-3
p(-3)=(-3)^3+3(-3)^2+a(-3)-12
-27+27-3a-12=0
-3a-12=0
3a=-12
a=-12/3
a=-4
