We have two cases:
1. $12-?=4$
2. $?-12=4$

The first case will give you the answer of 8 (since 12 - 8 = 4).
The second case will give you the answer of 16 (since 16 - 12 = 4).

16, since the inverse operation of subtraction is addition add 12 and 4.

For the square with side length n, the diagonal measures:

$d = \sqrt{2} *n$

<h3>How to get the length of the diagonal?</h3>

The sidelength of the square is n, and we want to get the length of the diagonal d.

Notice that the diagonal is the hypotenuse of a right triangle whose catheti measure n.

Then we can use the Pythagorean theorem, which says that the square of the hypotenuse is equal to the sum of the squares of the cathetus;

$d^2 = n^2 + n^2\\\\d^2 = 2n^2\\\\d = \sqrt{2n^2} \\\\d = \sqrt{2}*n$

That is the length of the diagonal.

What equation do you get when you solve z-m=z+bx for x?

Nimfa-mama [501]

X = -m/b.
Subtract z from both side and you get
-m= bx
Now divide both side by b and you get
-m/b= x

marshall27 [118]

In this problem the question asked is what principal should be invested on a rate of interest of 3.6% for 10 years to get the totals amount as 50000$
the formula for compound interest is
A=P*(1+R/100)^T
we shall replace the formula
50000=X*(1+3.6/100)^10
50000=x*(100/100+3.6/100)^10
50000=x*(103.6/100)^10
50000=X*(1.036)^10
50000=1.4242x
50000/1.4242=X
35107.42=X
