F(x)=x(x+1)
multiply each term in the parethesis by x.
x times x plus x; x times x equal x square.
so it would be:
x2 + x

If you know how much a penny weighs then you can weigh any amount of pennies and take that weight and divide by the weight of one penny, to get how many there are without counting all the coins.

The quadrilateral shown is rotated 90 degrees clockwise about the origin. In which quadrant is the image of the quadrilateral lo

iren2701 [21]

Answer:

Option (2). 1

Step-by-step explanation:

Coordinates of point A, B, C and D are,

A(-4, 4), B(-2, 4), C(-2, 1) and D(-4, 3).

Quadrilateral ABCD when rotated 90° clockwise about the origin,

Rule for the rotation of the vertices,

(x, y) → (y, -x)

Following the rule of rotation coordinates of the image points,

A(-4, 4) → A'(4, 4)

B(-2, 4) → B'(4, 2)

C(-2, 1) → C'(1, 2)

D(-4, 3) → D'(3, 4)

Since all image points have the positive coordinates (x and y coordinates), image quadrilateral A'B'C'D' will be located in 1st quadrant.

Option (2) is the correct option.

that is the answer if it's wrong then it must of been wrong question I gave answer to or I just got it wrong

Answer:

$-3x^4+3x^3+8x^2-2x-5$

Step-by-step explanation:

Here we need to move the negative sign to the rest of the variables, and then only add the ones with the same power:

$(-2x^4-2x^3+8x^2+2)-(x^4-5x^3+2x+7)\\-2x^4-2x^3+8x^2+2 - x^4+5x^3-2x-7$

And then move the variables with the same power closer together

$-2x^4-x^4-2x^3+5x^3+8x^2-2x+2-7$

See how -x^4 and -2x^4 are together?

All we have to do now is combine.

$-2x^4-x^4-2x^3+5x^3+8x^2-2x+2-7\\-3x^4+3x^3+8x^2-2x-5$

So our answer is $-3x^4+3x^3+8x^2-2x-5$
