8b + 16

2(6m +2)

I'm not really sure what the letters stand for in this context

Answers

Answer 1

the letters are a variable, when you have different variables you cannot plus or minus them like in this situation - 8b + 16

16 has no b's for plus 8b

2(6m +2) - in this expression we can multiply in which is 12m + 4

Answer 2
Ok so the letters are variables also can indicate any number so in the 8b+16 it is telling you that 8 times any number plus sixteen. And for the other variable m it is standing for when you multiply 2 times 6m which is 12m and then 2 times 2 which is four, so the inquisition for this equation would be 12m+4

please give me an example as well. I'd really appreciate it.

Answers

First, you would distribute the 0.4 through the parentheses

4x-6+8=-3-x

Then combine like terms

4x+2=-3-x

Get x on its own side,

5x=-5

Then divide by 5

x=-1

Check Answer by plugging in x

0.4(10(-1)-15)+8=-3-(-1)

0.4(-25)+8=-3+2

-10+8=-2

-2=-2

X=-1 so that should be the answer

Answer:

729

Step-by-step explanation:

Alright so our 2 big things here are order of operations and laws of exponets.

1st we need to find (-3)^4 and (-3)^2.

-3 raised to 4 is 81, and -3 raised to the 2nd power is 9.

So now our simplified equation is (81/9)^3.

Now we use the power of a quotient rule from the laws of exponets (look this name up and you'll easily find it).

So now our equation is (81^3)/(9^3). This equals 729.

Hope this helps!
