1. Each term in this polynomial has a common factor of $3x^3$ :

$12x^6-9x^4+18x^3=3x^3(4x^3-3x+6)$

2. Not sure what the "vertical method" is, but I would guess it refers to some way of visualizing the distributive property.

$(3x-5)(2x^2+7x-3)=3x(2x^2+7x-3)-5(2x^2+7x-3)$

$(3x-5)(2x^2+7x-3)=(6x^3+21x^2-9x)+(-10x^2-35x+15)$

$(3x-5)(2x^2+7x-3)=6x^3+11x^2-44x+15$

3. You can use the same approach as in (2), or recall that $(a+b)^2=a^2+2ab+b^2$ :

$(5x-4y)^2=(5x)^2+2(5x)(-4y)+(-4y)^2$

$(5x-4y)^2=25x^2-40xy+16y^2$

4. Recall that a difference of squares can be factored as $a^2-b^2=(a-b)(a+b)$ . So

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

$(2x^2-7)(2x^2+7)=4x^4-49$

What is the approximate area of the circle that fits perfectly inside of the square? Use Pi = 3.14 and round to the nearest tent

Pani-rosa [81]

Answer:

$19.625\text{ cm}^2$

Step-by-step explanation:

GIVEN: A square with base $5\text{ cm}$ , a circle that perfectly fits inside square.

TO FIND: Approximate area of circle.

SOLUTION:

Consider the figure attached.

let the radius of circle be $x\text{ cm}$

radius of circle $=\frac{\text{length of base of square}}{2}$

$x=\frac{5}{2}\text{ cm}$

$x=2.5\text{ cm}$

Area of circle $=\pi(radius)^2$

$=3.14\times(2.5)^2$

$=19.625\text{ cm}^2$

Hence the area of circle that perfectly fits inside the square is $19.625\text{ cm}^2$

What adds up to -54 and multiplies to -16

Kaylis [27]

X + y = -54
xy = -16

$xy = -16$
$\frac{xy}{x} = \frac[-16}{x}$
$y = \frac{-16}{x}$

$x + y = -54$
$x + \frac{-16}{x} = -54$
$\frac{x^{2}}{x} + \frac{-16}{x} = -54$
$\frac{x^{2} - 16}{x} = -54$
$x^{2} - 16 = -54x$
$x^{2} + 54x - 16 = 0$
$x = \frac{-(54) \± \sqrt{(54)^{2} - 4(1)(-16)}}{2(1)}$
$x = \frac{-54 \± \sqrt{2916 + 64}}{2}$
$x = \frac{-54 \± \sqrt{2980}}{2}$
$x = \frac{-54 \± 59.6}{2}$
$x = -27 \± 29.8$
$x = -27 + 29.8$ $or$ $x = -27 - 29.8$
$x = 2.8$ $or$ $x = 56.8$

x + y = -54
  2.8 + y = -54
- 2.8 - 2.8
y = -56.8
(x, y) = (2.8, -56.8)

or

  x + y = -54
  -56.8 + y = -54
+ 56.8 + 56.8
y = 2.8
  (x, y) = (-56.8, 2.8)

The two numbers that add up to -54 and multiply to -16 are -56.8 and 2.8.
