The answer to this question is -8r
Answer:
2^2 * 3 * 7
Step-by-step explanation:
First, divide by 2.
84 / 2 = 42
Divide by 2 again!
42 / 2 = 21
21 is divisible by 3, so divide by 3.
21 / 3 = 7
7 is prime, so we've reached the end of our little adventure!
84 = 2 * 2 * 3 * 7, or in exponents, 2^2 * 3 * 7.
Hope that helps!
You said that (xy) = 16, and (x+y) = 4 .
From the second equation you can get [ x = 4 - y ],
then substitude that for 'x' in the first equation, and
finally, rearrange the first equation to read
<u>x² - 4x + 16 = 0</u>
Don't even try to factor that quadratic equation. Go straight
to the quadratic formula, and the two solutions you find are ...
<em>x = 2 + i 2√3</em>
and
<em>x = 2 - i 2√3</em> .
Those are the two number that do what you want.
There are no <u>real</u> numbers that can do it.
Yes they are congruent because they have the same size angle and have the same parallel sides
Answer: it can be any equation that would equal 100
