26x³ - 12x² + 5x + 7

Step-by-step explanation:

  1. (2x³ - 3x + 11) - (3x² + 1) x (4 - 8x)
  2. 2x³ - 3x+11 - (12x² - 24x³ + 4 - 8x)
  3. 2x³ - 3x + 11 - 12x² + 24x³ - 4 + 8x
  4. 26x³ + 5x + 7 - 12x²

The plate is rotated 90° about the origin in the counterclockwise direction. In the image trapezoid, what are the coordinates of
Jet001 [13]

Answer:

The coordinates of the endpoints of the side congruent to side EF is:

E'(-8,-4) and F'(-5,-7).

Step-by-step explanation:

<em>" when point M (h, k) is rotated about the origin O through 90° in anticlockwise direction or we can say counter clockwise. The new position of point </em><em>M (h, k) will become M' (-k, h) "</em>

We are given a trapezoid such that the vertices of trapezoid are:

E(-4,8) , F(-7,5) , G(-4,3) , H(-2,5)

Then the new coordinates after the given transformation is:

E(-4,8) → E'(-8,-4)

F(-7,5) → F'(-5,-7)

G(-4,3) → G'(-3,-4)

H(-2,5) → H'(-5,-2)

Hence the coordinates of the endpoints of the side congruent to side EF is:

E'(-8,-4) and F'(-5,-7).

A number is multiplied by 16, and that product is added to 8. The sum is equal to the product of 4 and 10. Find the number.
Ymorist [56]

Your sum is 4 times 10, or 40. We want to end up with 40. Subtract 8 because you added 8 before to work backwards. You get 32. Divide by 16 because the opposite of multiplication is division. You would get 2.
