Answer:
Option D - 60
Step-by-step explanation:
Given : Connor made 9 shapes with straws. Each shape had 5 straws. Conor used 15 more straws to make more shapes.
To find : What is the total number of straws Connor used to make all the shapes?
Solution :
To make 1 shape Connor required 5 straws.
To make 9 shape connor required straws.
Now, there were 45 straws.
Conor used 15 more straws to make more shapes.
The total number of straws Connor used to make all the shapes are
Therefore, Option D is correct.
Cannor used 60 straws to make shapes.
First, we are going to find the conjugate of our complex number. Remember that to find the conjugate of a complex number we just need to keep the real part and change the sing of the imaginary part.
We can infer from our problem that the real part of our complex number is 3 and its imaginary part is . We are going to keep the real part 3 and change the imaginary part from positive to negative, so our conjugate is
.
Next, we are gong to multiply both the complex number and its conjugate using the distributive property:
Remember that , so:
We can conclude that the product of the multiplication of the complex number 3+3i and its conjugate, 3-3i, is 18.
