Answer:
(5 + 3i)(5 − 3i) = 34
Step-by-step explanation:
The multiplication of two identical binomials who have different symbol, can be solved using the factoring case of a difference of squares:
So, in this case:
Remember that 
So: 
We replace on the polynomial:
We must remember that 50 x 2 = 100. Multiplying numbers by 100 would be easier since all we have to do is add two zeros after. For example, 62 x100 = 6200.
Since we multiplied a number by 2, we must divide it by 2 after getting the product. To make this more clearer, for 12 x 50, for example, we have
12 x 50 = (12 x 100)/2 = 1200/2 = 600
Thus, the answer is C<span>.</span>
<em>Answer:</em>
<em>1cm = 50
</em>
<em>2 cm = 50 x 2
</em>
<em>3cm = 50 x 3
</em>
<em>and the inverse:50m = 50/50 = 1cm
</em>
<em>100m = 100/50 = 2cm
</em>
<em>150m = 150/50 = 3cm
</em>
<em>381m = 381/
</em>
Answer:
A
Step-by-step explanation:
This is a fraction equal to
6 miles ÷ 2 hours
We want a unit rate where
1 is in the denominator,
so we divide top and bottom by 2
6 miles ÷ 2 2 hours ÷ 2= 3 miles1 hour= 3 miles hour = 3 miles per hour
To the nearest percentage point, what percentage of students who play a sport don’t play a musical instrument?
First, using the information given, fill out the chart with the rest of the data (in the image attached)
Then find the number of students who play a sport and don’t play a musical instrument, which in the chart is 11
Place 11 over the total: 
and convert to a percentage:
44%
