Step-by-step explanation:
step 1. (a + b)(a - b) = a^2 - ab + ab - b^2 = a^2 - b^2.
step 2. this is always a binomial and never a trinomial and hence never a perfect square trinomual.
step 3. answer: never.
Answer:
Multiplying a complex number by a real number
Explanation:
For example, 2 times 3 + i is just 6 + 2i. Geometrically, when you double a complex number, just double the distance from the origin, 0. Similarly, when you multiply a complex number z by 1/2, the result will be half way between 0 and z.

The answer whould be 35 good luck
Answer:
80
Step-by-step explanation:
First of all, before you do anything to compute the answer, you can see that there is (–13/100) on both sides of the equation. You can cancel them out, since they're the same thing.
Now, you're left with:
This is also read as 0.8 is the same thing as [how many] hundredths.
You should know that 0.8 = eight tenths.
So if you move the decimal point right once, you'll get:
0.80
Which is also eighty hundredths.
Your answer would be:
which is 80.
To check your answer, you can also do:
80/100
Because the fraction bar can also be read as "divided by."
You will get 0.8.
