I bad at math so can someone help me hehe

Answer:

3 r 2 +9 r − 120

Step-by-step explanation:

Write the problem as a mathematical expression.

3 r ^2 + 9 r− 120

Factor  3  out of  3 r ^2 + 9 r − 120 .

Factor  3 out of  3 r ^2 .

3 ( r ^2 ) + 9 r − 120

Factor  3  out of  9 r .

3 ( r^ 2 ) + 3( 3 r ) − 120

Factor  3  out of  − 120 .

3 r ^2 + 3( 3 r ) + 3 ⋅ − 40

Factor  3 out of  3 r 2 + 3 ( 3 r ) .

3 ( r^2 + 3 r )+ 3 ⋅ − 40

Factor  3 out of  3 ( r 2 + 3 r ) + 3 ⋅ − 40 .

3 ( r^ 2 + 3 r − 40 )

Factor.

Factor  r^ 2 + 3 r − 40 using the AC method.

3 ( ( r − 5 ) ( r + 8 ) )

Remove unnecessary parentheses.

3 ( r − 5 ) ( r + 8 )

Hope this helps! :)

Answer:

The answer is C i got it right i am not lieing

Step-by-step explanation:

On Wednesday the hiker had the greatest elevation of 8.74 km.

We know the absolute value function of the modulus function always outputs a positive value irrespective of the sign of the input.

In piecewise terms  | x | = x for x ≥ 0 and | x | = - x for x < 0.

Given, Elevation represents the distance from sea level.

Positive numbers represent elevations that are above sea level and negative numbers represent elevations that are below sea level.

We know distance is always positive so if we look through the table on Wednesday the hiker has hiked - 8.75 km,

Now modulus of - 8.75 is | - 8.75 | = 8.75, so on Wednesday the hiker has the greatest distance covered.

LCM=780

Step-by-step explanation:

The least common denominator, also called lowest common denominator (LCD), of 60 and 13 is 780. Here is a math problem example where you need to know the LCD of 60 and 13 to solve: 3/60 + 2/13 = 780

Answer:

Average speed =80km/h

Step-by-step explanation:

Given data

initial odometer reading= 44 520 km

final odometer reading= 45 000 km

distance covered= final odometer reading-initial odometer reading

distance covered= 45 000 -44 520

distance covered=480km

time taken = 11-5= 6hours

we know that speed= distance /time

speed=480/6

speed= 80km/h

Step-by-step explanation:

Answer:

true

Step-by-step explanation:

took the quiz

The polynomial f(x) = 1 – 2x - 3x⁴ as x → infinity, f(x) → -infinity is true because the leading term is negative.

Polynomial is the combination of variables and constants systematically with "n" number of power in ascending or descending order.

[tex]\rm a_1x+a_2x^2+a_3x^3+a_4x^4..........a_nx^n[/tex]

We have a polynomial:

f(x) = 1 – 2x - 3x⁴

or

f(x) = - 3x⁴ - 2x + 1

As we increase the value of x the value of f(x) decreases because the leading term is negative.

Leading term = -3

Thus, the polynomial f(x) = 1 – 2x - 3x⁴ as x → infinity, f(x) → -infinity is true because the leading term is negative.

Answer:

i think 100 because its divisible by 2

Answer:

The area of the pool is 3 times the area of the cafeteria.

Step-by-step explanation:

Being that the dimension of the pool is 1.5 times larger than that of the cafeteria it means that 2 of it's sides are 1.5 times longer than the cafeterias. 2 x 1.5 = 3

So the area would be 3 times the area of the cafeteria.

Answer:

2 quarts

Step-by-step explanation:

In order to solve this problem we first need to calculate the total amount of lemonade, Tommy made in Cups. Since 1 quart holds 4 cups we simply multiply the 8 quarts that Tommy made by 4 like so...

8 * 4  = 32 cups of Lemonade

Now that we know that Tommy made a total of 32 cups of lemonade we can subtract the number of cups he sold each day from the total.

32 - 6 - 18 = 8 cups

Finally, we see that after selling 6 cups on Saturday and 18 cups on Sunday he has 8 cups left. Now we simply divide this by 4 to turn the cups back into quarts

8 / 4 = 2 quarts

Answer:

Las siguientes desigualdades expresan la condición real de la medida:

[tex]5.2\,cm < x <5.4\,cm[/tex], donde [tex]x[/tex] es la medida captada visualmente.

O de manera más rigurosa:

[tex]5.2\,cm \leq (5.3 \pm \epsilon)\,cm\leq 5.4\,cm[/tex], donde [tex]\epsilon[/tex] es el sesgo no captado por el observador.

Step-by-step explanation:

La graduación de la regla es la resolución visual de la medida, equivalente a 0.1 centímetros. Entonces, la medida obtenida de 5.3 centímetros es equivalente a un valor [tex]x[/tex] mayor que 5.2 centímetros y menor que 5.4 centímetros. Matemáticamente hablando, tenemos la siguiente desigualdad:

[tex]5.2\,cm < x <5.4\,cm[/tex], donde [tex]x[/tex] es la medida captada visualmente.

De manera más rigurosa, podemos describir el valor medido más un sesgo no captado por el observador ([tex]\epsilon[/tex]), medido en centímetros, dentro del intervalo citado:

[tex]5.2\,cm \leq (5.3 \pm \epsilon)\,cm\leq 5.4\,cm[/tex]
