Step-by-step explanation:
Complex number:
A complex number, given by:

Can be represented also as a point (x,y).
The modulus is given by:

Point z is at (negative 3, 1). What is the modulus of z?
. So

The modulus of z is 
Answer:
The second choice is the answer
Step-by-step explanation:
It is the answer because 4/4 is the same thing as 1/4 multiplied by 4.
Since it shows that x = 4/4 or 1 that means that 4/4 minus 1/4 will equal 3/4 or which it indicates the 3 block measured rectangle.
Hope this helps! :)
10 because it is teh number but with the opposite sign opposite of a posiive is a negative

having one rational solution is k is 8.
<h3>
What is a Quadratic Equation?</h3>
- Quadratic equations are the polynomial equations of degree 2 in one variable of the type
where a, b, c, ∈ R and a ≠ 0. - The standard form of a quadratic equation is
.
Here, the given equation is 
By comparing the given equation with the standard form of the quadratic equation we get,
a = 4
b = k
c = 4
The given quadratic is having one rational solution, which means 
Therefore,

Therefore, the value of k is 8.

Answer:
10 inches
Step-by-step explanation:
We can do this by first finding the number of inches Sandy and Leonid are. There are 12 inches in a foot so we can do 12×7 then add 7 to get Sandy's height. then we get 91 so sandy is 91 inches tall. Then we can do the same for Leonid so we do 12 × 8 +5. which is 101. Then we just subtract sandys height from leonids to get how much shorter she is which ends up being 10 inches shorter
