Since the triangle is right angled, we may use pythagoras theorem to find the third side.
Pythagoras theorem :-
KI^2 + JI^2 = KJ^2
substituting the known values in the formula,
x^2 + 3^2 = 5^2
x^2 + 9 = 25
x^2 = 25 - 9
x^2 = 16
x = √16
x = 4

Answer: The number is 8
Step-by-step explanation:
Let be "x" the certain number. Then "3 times a certain number" means that the number "x" is multiplied by 3. This is:
Now, "3 times a certain number is increased by 4" means that the we must add 4 to , in other words, this indicate an addition:
And finally "3 times a certain number is increased by 4 the result is 28" means that is equal to 28. Then the expression is:
To find the number "x", subtract 4 from both sides of the equation:
Dividing both sides of the equation by 3, you get that the number is:
Answer:
D
Step-by-step explanation:
If the least it can be is 12, that means that with will have to be equal to 12
so mark out a and b
It also said the least, this means it can not be less than it.
Put these two together and you get D) k is greater than or equal to 12
