If this is a perfect square trinomial, you want to look at your constant--36. the square root of 36 is 6, so your factors would be:

(x + 6)(x + 6) ... foil this, and see what your middle value is.
x² + 12x + 36 is your result. 12 is your middle term.

The circumference of a circular region is shown.what type of number best describes the diameter of the circle? Explain
Nutka1998 [239]
<span>Pi / 3.14</span><span>
Where pi is defined as the ratio of a circle’s circumference divided by the diameter of the its circle. Pi has a value which is 3.1416. This pi is a constant value expressed by the quotient of its circumference over the diameter. What type of number best describes the diameter is the pi. Hence, if we describe the diameter, diameter is the quotient of pi over the circumference of a circle by itself. It can’t change in value since for every solution and quotient of a circle each calculation gets 3.14 more or less. </span>

F(x)=2x^2+3x : evaluate the function, find f(-2)
egoroff_w [7]

Answer:

F(0) = 2

F(-1) = 7

F(2) = 4

Explanation:

Notice where the x's are in the function F(x)

For F(0) you sub in 0 wherever there is an x, ie:

F(0) = 2(0)2−3(0)+2 = 2

The same is applied for F(-1) and F(2)
