Answer:
-36
Step-by-step explanation:
1. Plug -3 into the equation given: -3(15-(-3)+2(-3)^2
2. Use Pemdas and first distribute the negative to negative three then distribute -3 to the rest of the parenthesis (final answer): -45-9 +2(-3)^2
3. Then put -3 to the power of 2 (which is 9) then multiply it by 2 (final answer): -45-9+18
4. Combine all like terms and you get the answer -36!
This is what is called a literal equation. Solve it for m just like you would solve any equation for x. Isolate the term with the variable you're looking for. Do this by subtracting 4cm from both sides to give you g - 4cm = -3m. Now we need to divide by -3 to get m alone:

. Or we could lose the negative on the 3 in the denominator like this:

and

. There you go! Any one of those last three would work. It just depends upon how your teacher wants you to express your answer.
Answer:
t > 20
Step-by-step explanation:
14 - 0.6t > 2
14 - 14 - 0.6t > 2 - 14
- 0.6t > - 12
- 0.6t ÷ - 0.6 > - 12 ÷ - 0.6
t > 20
17 is in the thousandths place, so we write it as a fraction over 1000.
17/1000
So we have:
46 17/1000
AB is 6
BC is 4
CD is 6
DA is 8
A is 45degrees
B is 130dgrees
C is 130degrees
D is 45degrees (about)
