Answer:
4
Step-by-step explanation:
i distributed the -2 to what's in the parentheses. that equal 0. I then moved the 4 to the zero so that it becomes positive. I just assumed that you were ask for Y
27x^2-81x-9x+27 In this case, just in your mind multiply 27 (coefficient of x^2) by the constant value 27(the end value of the quadratic trinomial). Then find factors that give you the value -90 when you add and 729 (27*27) when you multiply.
Factorise the values
27x( x-3)-9(x-3)
Which will give you
(27x-9)(x-3)
Answer:
false?
Step-by-step explanation:
If it’s v=1/3 *( a^2) * h
Divide both sides by (1/3)*h
v/(1/3*h) = a^2
Or
3v/h = a^2
Square root both sides
Sqrt(3v/h) = a
