[tex]4y^2+6x-2y^2+12x\\=4y^2-2y^2+6x+12x\\=2y^2+18x[/tex]
Answer:
2y^2 + 18xStep-by-step explanation:
4y^2 + 6x - 2y^2 + 12x = (4y^2 - 2y^2) + (6x + 12x) = 2y^2 + 18xDavid y Lorena montan bicicleta en circuitos de 6 km y 8 km respectivamente, pero estos circuitos tienen el mismo punto de partida. Si parten al mismo tiempo y recorren la misma distancia en el mismo tiempo, ¿después de cuántos kilómetros se vuelven a encontrar?
Answer:
Después de 24 kilómetros David y Lorena se vuelven a encontrar.
Step-by-step explanation:
El mínimo común múltiplo o también denominado cómo mcm, es el menor de los múltiplos comunes de varios números. Es decir, el mínimo común múltiplo de dos números o más números es el número más pequeño que es múltiplo de cada uno de los números.
Los múltiplos de un número son los que se obtienen cuando lo multiplicas por otros números. Un múltiplo común es un número que es múltiplo a la vez de dos o más números, es decir, es un múltiplo común a esos números.
Un método para calcular el mcm consiste en escribir los primeros múltiplos de cada número, señalar los múltiplos que sean comunes y elegir el múltiplo común más pequeño. En este caso:
6: 6; 12; 18; 24; 30; 36
8: 8; 16; 24; 32; 40; 48
Entonces el mcm entre 6 y 8 es 24.
Otro método para calcular el mcm consiste en descomponer en factores primos cada número. Después se debe elegir los factores comunes y no comunes elevados al mayor exponente y por último, multiplicar los factores elegidos.
Descomposición de 6= 2*3
Descomposición de 8= 2³
Entonces el mcm entre 6 y 8 es calculado como 2³*3 y da como resultado 24.
Entonces, después de 24 kilómetros David y Lorena se vuelven a encontrar.

Find the missing side. Round to the nearest tenth. (Please explain if you can)
The half of the moon facing the sun is always lit, but the different phases we view from Earth happen because:
the Earth moves to different positions around the Sun
we only see parts of the lit side as the moon goes around the Earth
only part of the light gets reflected to Earth
the spinning of the moon lets us see different amounts of light
Answer:
The half of the moon facing the sun is always lit, but the different phases we view from Earth happen because:
we only see parts of the lit side as the moon goes around the Earth.Step-by-step explanation:
The moon phases occur because the Sun lights different parts of the Moon as the Moon revolves around the Earth. So, we only see the parts of the Moon that are being lit while it orbits Earth.

Step-by-step explanation:
I took the quiz .
Solve
1. 3x(4-9)+7x-5=303
2. 5(2x+3)+12x=17
3. 7(4x-4)-20=38
1. 12x - 27x + 7x - 5 = 303
- 15x + 7x - 5 = 303
- 8x = 303 + 5
-8x = 308
x = - 38.5
2. 10x + 15 + 12x = 17
22x + 15 = 17
22x = 17 - 15
22x = 2
x = 0.0909090909
3.28x - 28 - 20 = 38
28x - 48 = 38
28x = 38 + 48
28x = 86
x = 3.07

What’s the radius, circumference, and area?
Answer:
radius= 4
circumference= 25.13
area= 50.27
Step-by-step explanation:
radius = diameter /2
= 8/2=4
circumference= 2πr
2× 22/7 ×4
=25.13
area= πr2
=22/7 ×4×4
= 50.27

which equation best matches the graph shown below ?
5x + 25
x + 5
What is x?
Answer:
D) 10
Step-by-step explanation:
5x + 25 + x + 5= 90
6x + 30 = 90
6x = 60
x= 10
Answer:
10
Step-by-step explanation:
5(10) =25=
50+25=75
10+5=15
75+15=90
That is a right angle so both equations added together need to equal 90.
