Answer:
72 cm
Step-by-step explanation:
You can solve this problem using the properties of the 45-45-90 right triangle. Assuming the 12 cm is a diagonal of the square, each side of the square can be modeled as x, and the diagonal will be x
.
This means
, so
.
Next, to find the area of the square you take the square of any of its sides. Since x is the length of one side, and
, you can square
to get the area. This is equal to
or 72 cm.
This is the concept of quadratic equations. We are required to find the missing factor in the partially factored quadratic equation given;
n(n-3)+2(n-3)=()(n-3)
here we proceed as follows;
n(n-3)+2(n-3)
when we factor this we get:
(n-3)(n+2)
this can be written as:
(n+2)(n-3)
The answer is (n+2)
Input the fraction = 95/8
Integer =11
Fraction part = 7/8
Answer = 11.875
B hope this helps good luck
