Answer:
See explanation
Explanation:
When an element tends to lose its valence electrons in chemical reactions, it behaves more like a metal.
When an element tends to gain valence electrons in chemical reactions, it behaves more like a nonmetal.
Metalloids have properties intermediate between those of pure metals and pure nonmetals. Usually, metalloids appear in groups where they are sandwiched between nonmetals and metals such as in groups 13, 14 and 15.

Hello oddworld7836!
Factor the expression into an equivalent form 12y² - 75.
By observing the expression, we can see that, 3 is the only common factor in both the terms of the expression. So, take the common factor 3 out.
Now, look at (4y² - 25). They don't have any common factors but they appear in the form of the algebraic identity ⇨ a² - b² = (a + b) (a - b). Here,
- a² = 4, a = 2 (√a² = ✓4 = 2)
- b² = 25, b = 5 (√b² = ✓25 = 5)
So, the (4y² + 25) becomes...
Now, bring the 3 (common factor) & rewrite the complete expression.
We can't further simplify it. Also, remember that the simplified form of an expression is equivalent to the expression. So, 3 (2y - 5) (2y + 5) is equivalent to 12y² - 75.
