Factor completely x^3+7x^2-2x-14

Mathematics
1 answer:
Ahat [919]3 years ago
5 0

Answer:

Step-by-step explanation:

Notice that x + 7 is a factor of the first two terms, and that it is also a factor of the last two terms.  Thus,

x^3+7x^2-2x-14 = (x + 7)(x^2 - 2).

We could carry the factoring further, as follows:

(x + 7)(x^2 - 2) = (x + 7)(x - √2)(x + √2)

<u>Rectangle area:</u>

  • A = lw

<u>Given:</u>

  • l = 12 ft, A = 300 ft²

<u>Find w:</u>

  • 12w = 300
  • w = 300/12
  • w = 25 ft

Mrrafil [7]

Answer:

(-5.4,3) is in the IInd quadrant, (3,-5.4) is in the IVth quadrant.

Mirror image of (-5.4,3)

Step-by-step explanation:

(a) The points are (-5.4,3) and (3,-5.4).

The origin is the center point of the graph. The right side of the x axis is positive the left side is negative. The upward direction from the origin is the positive y axis and the downward direction is negative y axis.

For (-5.4,3) the x axis location is -5.4 and the y axis location is 3

For (3,-5.4) the x axis location is 3 and the y axis location is -5.4

So, the point (-5.4,3) is in the IInd quadrant and the point (3,-5.4) is in the IVth quadrant.

(b) A mirror image with respect to y axis is the point on the opposite side of the quadrant where the point on x axis has changed the sign and y axis point remains constant.

The point (5.4,3) is the mirror image of the point (-5.4,3) with respect to y axis.

The point (3,-5.4) has the x and y points interchanged and the sign of the point on the y axis has changed when comparing to (5.4,3).
