Use synthetic division to evaluate (3x2 − 6x + 3) ÷ (x − 1). 3x − 9 3x2 − 3x 3x − 3 3x2 − 6

Viefleur [7K]

Answer:

$\frac{\left(3x^2-6x+3\right)}{\left(x-1\right)3x-93x^2-3x^3x-33x^2-6}: -\frac{\left(x-1\right)^2}{x^4+41x^2+x+2}$
$\frac{3x^2-6x+3}{\left(x-1\right)\cdot \:3x-126x^2-3x^3x-6}$
$\frac{3\left(x-1\right)^2}{\left(x-1\right)\cdot \:3x-126x^2-3x^3x-6}$
$\frac{3\left(x-1\right)^2}{-3\left(x^4+41x^2+x+2\right)}$
$\frac{\left(x-1\right)^2}{-\left(x^4+41x^2+x+2\right)}$
$-\frac{\left(x-1\right)^2}{x^4+41x^2+x+2}$

In terms of x, find an expression that represents the area of the shaded region. The outer square has side lengths of (x+5) and

VLD [36.1K]

The area of the outer square = (x+5)² = x² + 10x + 25

The area of the inner square = (x-2)² = x² - 4x + 4

The area of the shaded region = (x² + 10x + 25) - (x² - 4x + 4)
= x² + 10x + 25 - x² + 4x - 4
= 14x + 21 square units

A necklace has and matching bracelet have two types of beads. The necklace has 12 large beads and 8 small beads and weighs 88 gr

miv72 [106K]

Weight of one large bead is 1.5 grams and weight of one small bead is 8.75 grams.

Step-by-step explanation:

Let,

Weight of one large bead = x

Weight of one small bead = y

According to given statement;

12x+8y=88 Eqn 1

5x+2y=25 Eqn 2

Multiplying Eqn 2 by 4

$4(5x+2y=25)\\20x+8y=100\ \ \ Eqn\ 3\\$

Subtracting Eqn 1 from Eqn 3

$(20x+8y)-(12x+8y)=100-88\\20x+8y-12x-8y=12\\8x=12$

Dividing both sides by 8

$\frac{8x}{8}=\frac{12}{8}\\x=1.5$

Putting x=1.5 in Eqn 1

$12(1.5)+8y=88\\18+8y=88\\8y=88-18\\8y=70$

Dividing both sides by 8

$\frac{8y}{8}=\frac{70}{8}\\y=8.75$

Weight of one large bead is 1.5 grams and weight of one small bead is 8.75 grams.
