Please, group your sets of numbers, using { } notation or at least semicolons ( ; ). Thanks.
Looking at what I think is your first set: { sqrt(4), sqrt(5), sqrt(16) }
Square each of these and then subst. the results into the Pythagorean Theorem:
{ 4, 5, 16 } Do 4 and 5 when added together result in 16? NO.
Therefore, { sqrt(4), sqrt(5), sqrt(16) } does not produce a right triangle.
Your turn. Pick out the next 3 numbers and test them using the Pyth. Thm.
First convert everything into inches.
1 foot = 12 in
5 feet = 5*12 = 60 in
12 feet = 12*12 = 144 in
Now add them together
60 + 9 + 144 + 3 = 216 in
or
18 feet
Hope this helps :)
Each was 10 inches because she had 95 and 95-15=40 divided by 4 = 10
1:5=1/5
1/5=20/100
20/100= 20%
20% of bag is pink marbles
Second one is correct, that is an identity.
Third one is a contradiction:
6x - 15 = 3 * (2x - 6) ------> 6x - 15 = 6x - 18
Fourth one:
5x - 3 * (x - 4) = 2 * (x - 6) ---> 5x - 3x + 12 = 2x - 12 ---> 2x + 12 = 2x -12
So this is a contradiction as well.
