Using synthetic division, what is the width of the rectangle? Brainliest!! 5 stars, thanks.
Answers
Hi there!
[tex]\large\boxed{5x^{2} + 4x - 6}[/tex]
**Work pictured below**
Since x + 3 is one of the factors, set it equal to zero to find the root:
x + 3 = 0
x = -3
Use -3 in the synthetic division process to solve for the width.
Use the coefficients of 5x³ + 19x² + 6x - 18 to do synthetic division:
5, 19, 6, -18
To do synthetic division, arrange the numbers in the polynomial as shown with the root outside of the diagram.
1. Bring down the first number
2. Multiply by the root and add that number to the next number. Bring the sum down to the bottom.
3. Repeat until finished with all numbers. If a number is a perfect root, it will have a remainder of 0 at the last number.
In this instance, doing so produced the numbers 5, 4 and -6. There was also no remainder as the last number produced 0. Therefore, the width of the rectangle is:
5x² + 4x - 6 **First term is always one degree LESS than you started with**
Answer:
5x^2 + 4x - 6
Step-by-step explanation:
(5x^3 + 19x^2 + 6x - 18)/(x + 3)
-3 | 5 19 6 -18
-15 -12 18
5 4 -6 0
(5x^3 + 19x^2 + 6x - 18)/(x + 3) = 5x^2 + 4x - 6

A rubber bouncy ball is bouncing up and down such that the ball's distance, d, in feet above the ground is given by the inequality
Which of the following graphs shows all the possible distances?
Answers
Answer: Option D.
Step-by-step explanation:
We have the inequality:
Id - 3.5I ≤ 1.5
remember that : IxI < d means that:
-d < x < d
Now let's find the possible values of d, breaking the absolute value we have that:
-1.5 ≤ d - 3.5 ≤ 1.5
adding 3.5 in each part, we have:
-1.5 + 3.5 ≤ d - 3.5 + 3.5 ≤ 1.5 + 3.5
2 ≤ d ≤ 5
Then d can be any value in the set [2, 5]
Then the correct graph is D, because the purple line starts at 2, and ends at 5.

PLEASE HELP!! i'm struggling sm :/
Answers
Answer:
Check boxes 3, 4, 6, and 8.
Step-by-step explanation:
We have the equation:
[tex]y=-3x+2[/tex]
And we want to select all equations that are perpendicular to the above equation.
Remember that perpendicular lines have slopes who are negative reciprocals of each other.
Therefore, the slope of our equations must be the negative reciprocal of -3.
The negative reciprocal of -3 is 1/3. We flipped -3 to -1/3, and then multiplied by a negative.
Therefore, any equation with a slope of 1/3 is perpendicular to our original line.
Therefore, we will check boxes 3, 4, 6, and 8.

Answer:
A pizza shop sells pizzas that are 10 inches orr larger. A 10-inch cheese pizza costs $8 and each additional costs $1.50 and each additional topping costs $0.75.
The equation that represents the cost of a pizza is:
P = $10 + $1.50a + $0.75b
Where 'a' represents the number additional inches and 'b' represents the number of additional toppings.

We can rewrite it as such:
[tex]=\sqrt{-1\cdot 98} =\sqrt{-1\cdot 49\cdot2}=\sqrt{-1}\cdot\sqrt{49}\cdot\sqrt{2}[/tex]

a cuboid with a volume of 374cm^3 has dimensions
Answers
Answer:
2 x 11 x 17 = L x W x H
Step-by-step explanation:
x² + 12 (8) - 160 = 0
8(8) + 96 -160 = 0
8(8) + 96 -160
160 -160 = 0
x² + 12x -160 = 0
x² + 8 × - 20 = 0
(x +8) (x-20)
2( x+3 ) × (x+9) = 374
(x+3) × (x+9) = 374 ÷ 2
(x+3)× (x+ 9) = 187
x² = 184 - 9
x² = 175
x = 175/25
x = 8
Formula of Volume of Cuboid
V = L ×W × H
V = 2 × (x+3) × (x+9)
2 ( 8+3 ) × ( 8+ 9)
2 (11) × (17)
x + 3 = 11
x + 9 = 17
Volume L × W × H
2 × 11 × 17 = 374cm³
satisfies the equation

Step-by-step explanation:
Un introductor de carne de res en canal compró mil piezas a 200 pesos cada. Vendió 600 de ellas obteniendo una ganancia del 25 %. ¿A qué precio deberá vender las piezas restantes si la utilidad promedio del lote completo (de las mil piezas) debe ser del 30 %? ¿Cuál es su utilidad por la venta de las mil piezas?
Answers
Responder:
275 pesos
60.000 pesos
Explicación paso a paso:
Dado que :
Número de piezas = 1000
Precio por pieza = 200
600 piezas vendidas con un beneficio del 25%
(100 + 25)% = 125% de 200
1,25 * 200 = 250 cada uno
Precio de 600:
(600 * 250) = 150 000
Para un beneficio del 30% de todo el lote:
(100 + 30)% = 130% * 200 = 260
(1000 * 260) = 260 000
Precio de los 400 restantes:
(260.000 - 150.000) / 400 = 110.000 / 400 = 275 peso
Beneficio de la venta:
Precio de venta:
(150.000 + 110000) = 260000 pesos
Precio de compra :
(1000 * 200) = 200.000 pesos
260.000 - 200.000 = 60.000 pesos
