Expressing a fraction in the simplest form means to simplify common factor in the numerator and the denominator.
To do so, let's find the prime factorization of both:

So, we can write the fraction as

We can simplify (i.e. cancel) a factor 2 appearing both in the numerator and denominator. We're left with

Answer:
30
Step-by-step explanation: when you add all of the ones in the center up even the ones that aren't complete you get 30.
Answer:
Step-by-step explanation:
<u>Factoring the given expression:</u>
- -45x³ - 60x² - 20x =
- -5x(9x² + 12x + 4) =
- -5x(9x² + 6x + 6x + 4) =
- -5x(3x(3x + 2) + 2(3x + 2))
- -5x(3x + 2)(3x + 2)
- or
- -5x(3x+2)²
5x6-5<-------
5x6=30
30-5=25
there you go (The first expression is the answer-hope it helps!)
The value of x is 78 Degrees. The angles are complementary so they are equal.
