What value in place of the question mark makes the polynomial below a perfect square trinomial 9x^2+? x+64

The middle term would be 48x

Step-by-step explanation:

In order to find this, we need to take the squares of the end terms and put them in a perfect square. Then we can distribute to find the middle term.

(3x + 8)^2

(3x + 8)(3x + 8)

9x^2 + 24x + 24x + 64

9x^2 + 48x + 64

where's the diagrams?

the answer for this question is : 360°

step-by-step explanation:

we have been given a triangle   we need to tell which one of these is a triangle below to map onto itself.

360° rotation is the complete rotation which eventually leads to the same figure which is given.

the correct will be, that is 360° that will cause the triangle below to map onto itself.
