Answer:
I'm pretty sure it's both, but I can see this is a summative exam/test so I'm really sorry if it's wrong.
Answer:
Did you mean the diagonal are equal in length and bisect each other?
In that case, it is parallelogram.
Hope this helps!

Answer:
Therefore the two values required are 2.08 and -11.08.
Step-by-step explanation:
i) f(x) = 
+ 10x - 12 is a quadratic equation and a quadratic equation will have two roots whose values when substituted in to the given quadratic equation will give the value.
ii) The question is therefore essentially asking us to find the roots of the given quadratic equation.
This can be done by equating the given quadratic equation to zero and then solving the equation for its roots.
∴ + 10x -12 = 0 ⇒ x = (-10 ± 
) ÷ 2
= (-10 ± 12.166)÷2 = 2.08, -11.08
Therefore the two values required are 2.08 and -11.08
What do you need to solve for?
X=r-4/7-s
S=-r/x+4/x+7
R=-sx+7x+4
Answer:
C = 20
Step-by-step explanation:
The sum of the angles of a triangle is 180
73+87+c =180
Combine like terms
160 +c = 180
subtract 160 from each side
160+c-160 = 180-160
C = 20
