Can I have help with geometry?

Answer 1

Sure what is your question?

Answer 2

To prove each statement by contradiction, do the following:
A. Assume the contradiction is false, write the negated assumption.
B. Show that the negated assumption.
C. Make a valid conclusion about the original statement.
For any real number x, 2( 10x +3) not equal 5(4x-3)

Answer 11

So to solve a problem by contradiction, you take the statement you want to prove and assume it is false. For this problem, you want to show that for any real number x, 2(10x + 3) is not equal to 5(4x - 3)
So we want to assume this is false:

Suppose there is a real number x such that 2(10x + 3) = 5(4x - 3).

Then we want to find a reason this can't be true. In this case:

Then for that value x, 20x + 6 = 20x - 15
Therefore 6 = -15
6 is not equal to -15
Therefore, there is no value of x for which 2(10x + 3) = 5(4x - 3).

Answer 12

so how did u get -15

Answer 13

Expanding 5(4x - 3)

5(4x - 3) = 5*4x - 5*3 = 20x - 15

Answer 14

okay i see now
