Answer:

The number to add is (11/2)^2 = 121/4

Step-by-step explanation:

Here, we want to know the number that will complete the square

We rewrite the equation as follows;

x^2 + 11x = -30

x^2 + 11x + (11/2)^2 = -30 + (11/2)^2

x^2 + 11x + 121/4 = -30 + 121/4

Phantasy [73]

Answer:

Step-by-step explanation:

The three angles of a triangle always have to equal 180 in the end, so if you use the method which is the 4 in this instance, it is an obtuse angle that is equal to the top and left angle. You can add 1 and 2 to get 4, and do 4-3 to get 1+2, So, 4=1+2.
