Grade 11 Can anyone please help me with these Math questions?

Soon as possible!!

If , p (x) = 3x^2 - 2x + 1 , find p(–4).

Find p(–3) if p(x) = 4x^3 – 5x^2 + 7x – 10.

one set of data has more variation than the other. hope this !

5 + 8 +7 + 4 + 0 +1 = 25

step-by-step explanation:

answer: (-8,4) are the coordinates of a

step-by-step explanation:

let the side of square abcd is x .

thus the area of square abcd is .

now, by the diagram area of triangle ead= 1/2 × ea × ad = 1/2 × ea × x

( because ad is the side of square)

and, according to the question,

the areas of square abcd and right ead are equal.

⇒

⇒ea=2x

thus, ea: ab=2: 1

therefore, point a divides line segment eb into the ratio 2: 1.

⇒ by sectional formula coordinates of a are,

=

=

=(-8, 4)

thus the coordinates of a are (-8,4)
