1) Identify the statement you want to prove is true

2) Assume temporarily that the statement is false; assume the opposite is true

3) Obtain statements that logically follow from your assumption.

4) Reason logically until you reach a contradiction of a known fact.

5) Point out that your assumption must be false, and the statement must then be true.

12x + 18=1, as you cannot combine -3x and 1 to get -2
To continue:
12x = -17
x = -17/12

Can you help me with this problem

2A=bh (multiply both sides by 2)
2A/h=b (divide by h)

hope this helps

Do you think a negative number raised to an even power will be positive or negative? Explain.

Tanya [424]

Answer:

A negative number taken to an even power gives a positive result (because the pairs of negatives cancel), and a negative number taken to an odd power gives a negative result (because, after cancelling, there will be one minus sign left over).
