Answer:
i think 100 because its divisible by 2
The sum of 3 terms in A. P.is - 3 and their product is 8, then sum of squares of the numbers is
sum of the numbers = - 3
Product of the numbers = 8
Find:sum of squares of the numbers
Solution:Let the three terms be a - d , a , a + d.
sum of the numbers = - 3
→ a - d + a + a + d = - 3
→ 3a = - 3
→ a = - 3/3
→ a = - 1
Also,
Product of the numbers = 8
→ (a - d) * (a) * (a + d) = 8
Putting the value of a and using (a + b) * (a - b) = a² - b² we get,
→ [ (- 1)² - d² ] = 8/ - 1
→ 1 - d² = - 8
→ 1 + 8 = d²
→ 9 = d²
→ d = 3
Hence,
a - d = - 1 - 3 = - 4 a = - 1 a + d = - 1 + 3 = 2Now,
Finding Sum of their squares :
→ (a - d)² + a² + (a + d)²
→ ( - 4)² + ( - 1)² + (2)²
→ 16 + 1 + 4
→ 21
Hence, the sum of the squares of the three terms is 21.
I hope it will help you.

3r2 + 9r- 120
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! :)

HELP!!!!!!!!!!!!! DeMarcus went to a restaurant with his debate team. DeMarcus's order came to $15.32. If DeMarcus wants to leave a 20% tip, how much will DeMarcus pay? How much was the tip? Show your Math and Explain how you used math to determine your answer.
Answer:
DeMarcus will pay $18.38. His tip is $3.06.
Step-by-step explanation:
Change the percent into a decimal: 20% = 0.20
Multiply the decimal by $15.32: 0.20 x 15.32 = $3.06
Add the tip to the total: 15.32 + 3.06 = $18.38

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.
A and B are two similar 2D shapes.

Mr. Bishop and his family leave on a car trip Saturday morning at 5am and arrive at their destination at 11am. When he began the trip the car's odometer read 44 520 km and when he arrived it read 45 000 km. What was the average speed for the trip?
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

Curved lips he just can't disguise.

Step-by-step explanation:
Se midió la longitud de un segmento con una regla que tiene la graduación hasta un milímetro y se obtuvo la medida 5.3 cm. ¿Entre qué valores está la medida real x cm? Expresa tu respuesta con una desigualdad.
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]
