The answer to your question is true
The answer is (4, 3)! :)
Explanation:
3 < 2(4) - 5
3 < 8 - 5
3 < 3 IS NOT TRUE
(Could I get brainliest too?)
Answer:
25 cm.
Step-by-step explanation:
If the hypotenuse is x cm long the 2 legs are x-5 and x-10 cm long.
So by the Pythagoras theorem:
x^2 = (x - 5)^2 + (x - 10)^2
x^2 = x^2 - 10x + 25 + x^2 - 20x + 100
x^2 - 30x + 125 = 0
(x - 5)(x - 25) = 0
x = 5, 25
We can discard x = 5 because that would make the lengths of the legs negative so the hypotenuse = 25 cm long.
Hmm,
ok,
complete square ok
wait wat
he went from
(x-3)²=16 to
x-3=16
?????
he square rooted the left side only
he has to do it to both sides
he should have done
(x-3)²=16
x-3=+/-4
x=3+/-4
x=7 or -1
