Answer:
19x+8
Step-by-step explanation:
First distribute 2 into the parenthesis which will equal 12x+8+7x
Than add like terms 12x+7x = 19x
Than youre left with 19x+8 and that is the answer :}
Answer:
19x+8
Step-by-step explanation:
You multiply everything in the parenthesis by 2 and then get rid of the parenthesis so then the equation will be 12x+8+7x. Then you add 12x and 7x together because you can't add together a normal number and a variable. Then the equation will be 19x+8. This is the final equation.

La opción correcta es;
x² - 4·x·y + 4·y²
Step-by-step explanation:
La ecuación dada es (x - 2·y) ²
(x - 2·y) ² = (x - 2·y) × (x - 2·y) = x·x + x × (-2·y) + (-2·y) × x + (-2·Y) × (-2·y)
Lo que da;
(x - 2·y) ² = x² - x × 2·y - 2·y × x + (-2·y) ²
De lo que tenemos;
(x - 2·y) ² = x² - 2·y × x - 2·y × x + 4·y² = x² - 4·y × x + 4·y²
∴ (x - 2·y) ² = x² - 4·y × x + 4·y² = x² - 4·x · y + 4·y²
Y el resultado del cuadrado simplificado es (x - ·y) ² = x² - 4·y × x + 4·y² = x² - 4 · x · y + 4·y²
La opción correcta es (x - 2·y) ² = x² - 4·x · y + 4·y².

what is the coefficient of a^8b^2 in the expansion (1/3a^2 - 4b)^6
Answers
Step-by-step explanation:
(1/3a^2-4b)^6 for such an expansion the general term is
[tex]tr + 1 = \binom{6}{r} \times ( \frac{1}{3} {a}^{2} ) ^{6 - r} \times (4b)^{r} [/tex]
we want b^2 so r=2
so the formula transform to:
C6,2*(1/3)^4*a^8*4^2*b^2 so the coefficient of a^8b^2 is

Si Leo crea el mayor número de equipos posible, ¿cuántos defensas habrá en cada equipo?
Answers
Answer:
5 defensores
Step-by-step explanation:
La pregunta correcta es la siguiente;
Hay 32 delanteros y 80 defensas en la liga de baloncesto de Leo. Leo debe incluir a todos los jugadores en un equipo y quiere que cada equipo tenga el mismo número de delanteros y el mismo número de defensas. Si Leo crea el mayor número de equipos posible, ¿cuántos defensas habrá en cada equipo?
Responda como sigue;
Ahora queremos saber el número de defensas que deberíamos tener por equipo.
La respuesta a esta pregunta es simplemente encontrar la relación entre el número de delanteros y el número de defensores.
matemáticamente,
eso sería 32:80 = 2: 5 Entonces esto significa que por cada 2 delanteros en un equipo, debería haber 5 defensores
a certain map shows two roads. road a is 1 1/4 miles long but is 1 1/2 inches long on the map. what the unit rate for inches per miles on this map? if road b is 10 miles long, how long is road b on the map?
Answers
Answer:
30 inches
Step-by-step explanation:
Length of road A = 1¼ miles
Length of road A on map = 1½ inches
Unit rate for inches per miles on the map = 1½ inches ÷ 1¼ miles = ³/2 ÷ ⁵/4 = ³/2 × ⅘ = ⁶/5 inches per mile
Length big Road B on map:
Road B actual length = 10 miles
Thus, using the unit rate of ⁶/5 inches to 1 mile, length of road B on map would be calculated as shown below:
⁶/5 × 10 = 6*5 = 30 inches
Road B is 30 inches long on the map.

open the parenthesis
8x - 8 + 2 = 4x - 8
add 8 to both sides of the equation
8x - 8 + 2 + 8 = 4x - 8 + 8
combine like terms
8x + 2 = 4x
subtract 4x from both sides of the equation
8x - 4x + 2 = 0
4x + 2 = 0
subtract 2 from both sides of the equation
4x + 2 - 2 = 0 -2
4x = -2
divide both sides by 4
4x/4 = -2/4
x = -1/2

Answer:
145
Step-by-step explanation:
180-137=43
43+102=145
Answer The answer is 145 because, as you see you need a 180 degree angle, so you have 137 and you need to make those two angles 180 so 180-137=43 so then you got 43+102 so that's 145 then you have that other angle so that'll be 35, so the ? mark will be 145 since that 180-35

Which equation shows a proportional relationship between x and y?
y = 16
y = 7x
y=−7x−2
y = 9x + 1
Answers
The equation that shows a proportional relationship is y = 7x.
How to find the equation that is proportional?Two variables have a proportional relationship if all the ratios of the variables are equivalent.
In other words, a proportional relationship is one in which two quantities vary directly with each other.
Therefore, a proportional relationship can be represented as y = kx.
where
k = constant of proportionalitythe variables are x and yTherefore, y varies directly as x in a proportional relationship.
Hence, the equation that shows proportional relationship is y = 7x as 7 is the constant of proportionality. y and x are the variables.
