Answer:
1) NP
2) P
3) NP
4) P
5) P
Step-by-step explanation:
re-write all the pairs into fractions
1.) {4 x <u>5</u> = 20} and {6 x <u>4</u> = 24} <u>5 </u>≠ <u>4</u>
- (basically both the underlined numbers need to be the same)
I can do an explanation for each one if you need; just comment, cause I'll be on here for a while. Good luck! :D
It is true. That is usually proved in every geometry course. It is one of the fundamental theorems of elementary geometry.

B) x = 2
Step-by-step explanation:
1 + 1 = x
2 = x

Answer:
a) The possible solutions are:
x=7 and x=-3
b)The extraneous solution
is x=
Step-by-step explanation:
The last step gives us the possible solutions.
By the zero product property,
This implies that:
The original equation is
We substitute x=-3 to get;
This not true, therefore x=-3 is an extraneous solution.
We substitute x=7
Therefore x=7 is the only solution.
