Hi friend
(3-2i)(3+2i)
as (a+b)(a-b) =a²-b²
3²-(2i)²
=9-(4*-1)
=9-(-4)
=9+4
=13
Hope this helps you!
Answer:
Well I answered it
Step-by-step explanation:
So first thing you are going to do is add, so we are going to use PEMDAS
add the 5+4 and you get 9 then we're going to take that 7 and add the 9 and 7 so that gives us 16 now the 11² so that means we are doing 11 two times i think so then 11 times 2 is 22 take that 16 and subtract so 22 take away 16 is 5 now idk what to do with the (4) and (3) at the bottom i hope this helped and i think this is what you have to do if not please tell me what grade this is so i know
The number of miles he drove for a cost of $30.50 is 275 miles.
<h3 /><h3>How to find the number of miles using linear equation?</h3>
Using linear equation,
y = mx + b
where
Therefore,
9 cents = $0.09
y = 35.50 + 0.09x
where
x = number of miles drove
y = total cost
Therefore,
60.25 = 35.50 + 0.09x
60.25 - 35.50 = 0.09x
24.75 = 0.09x
x = 24.75 / 0.09
x = 275 miles

Opposite angles have the same measures. This allows you to set and solve the following equations:
To solve both equations, let's move all the terms involving the variables on the left hand side, and all constant terms on the right hand side:
Sum like terms:
Divide the first equation by 2 and the second by -4:
To write an expression that shows 9 * 475 multiply using expanded form an distributive property we break 475 into three numbers
475 can be break into 400 + 70 + 5
Now we multiply by 9
9 x 475
9 x (400 + 70 + 5) (expanded form of 475)
We use distributive property here.
We distribute 9 inside the parenthesis
9 x 400 + 9 x 70 + 9 x 5
3600 + 630 + 45
4,275
