Answer:
129.99+412.50=$542.49
Step-by-step explanation:
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
______________________
•°• value of x is 4cm
For this case we have the following expression:
Where,
k: it is a variable
What we must do is rewrite the expression in word form.
We then have to rewrite the expression:
seven less than the value of k.
Answer:
A phrase describes the variable expression k-7 is:
seven less than the value of k.
K-7= 7 less than k It's like if your wording backwards
To solve for x, you need to isolate/get x by itself in the equation:
Square ² both sides to get rid of the square root √
x - 2 = 0 Add 2 on both sides
x - 2 + 2 = 0 + 2
x = 2
