If you type "sorry" after "finals help," that perhaps indicates that you know you should not be asking for help with an exam. Otherwise your exam grade will not reflect your true knowledge and skill correctly.

Here this person starts with $145. So, immediately discard the 2nd and 4th possible answers.

It appears that the 1st and 3rd possible answers are identical. Double-check the original problem, please.

I WILL GIVE 20 POINTS TO THOSE WHO ANSWER THIS QUESTION RIGHT NOOOO SCAMS AND EXPLAIN WHY THAT IS THE ANSWER

professor190 [17]

Answer:

Step-by-step explanation:

The formula for the Pythagorean Theorem is:

$\sqrt{a^2+b^2}=c$

Now,

A=7

B=24

7x7=49

24x24=576

Add,

576+49=625

Last,

Take the square root of 625

The square root of 625 is 25

c=25

To Check if the hypotenuse is correct:

$a^2+b^2=c^2$

$7^2+24^2=25^2$

7x7=49

24x24=576

25x25=625

49+576=625

625=625,

Therefore the hypotenuse is 25.
