Simplify the expression:
2(3 + 2m)
Answers
Answer:
4m + 6
Step-by-step explanation:
Hello There!
We can simplify the expression by distributing the 2 to what is inside of the parenthesis ( 3 and 2m)
3 * 2 = 6
2 * 2m = 4m
so the expression 2(3 + 2m) simplified would be
4m + 6
Answer: 6+4m
Step-by-step explanation:
Let's take our equation first
2(3+2m)
Now we need to distribute the 2 into the parenthesis'
This would mean we need to multiply 2 by 3 and 2m
our answer would be
6+4m

What’s the volume of the prism ?
Answers
Answer:
63[tex]cm^{3}[/tex]
Step-by-step explanation:
To find the volume of this prism, all you need to do is multiply the height, the width, and the length of the prism. The height is 3, the length is 7, and the width is 3. So 3·3·7=9·7=63. Now we have to add the label, which is cm. We are multiplying 3cm by 3cm by 7cm, which makes it [tex]cm^{3}[/tex]. Now you just multiply [tex]cm^{3}[/tex] and 63 together, which gets you 63[tex]cm^{3}[/tex].

1. 3x(4-9)+7x-5=303
2. 5(2x+3)+12x=17
3. 7(4x-4)-20=38
Answers
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

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.
