Answer:
Ang panahon o kalagayan ng panahon ay ang paglalarawan sa kalagayan at katangiang pangkalikasan sa labas ng tahanan, gusali o anumang tirahan ng tao, hayop, halaman at iba pang mga nilalang, na ayon sa singaw ng kalawakan o ng atmospera ng daigdig. Tumutukoy ito sa kainitan, katuyuan, kalamigan, kabasaan, katahimikan, pagka-maaraw, pagkamahangin, o pagiging maulan sa isang pook, sa isang takdang oras, na maaaring magbago. Nararamdaman, naririnig, nakikita ng tao ang epekto ng panahon at maging ang pagbabago sa kalagayan nito. Nasusukat din ang panahon sa pamamagitan ng mga termometro, barometro, barograpo, sikrometro o higrometro, panukat ng hangin, anemometro, at mga panukat ng ulan. Depende rin ang taya ng panahon sa pagdating ng kapanahunan ng tag-init, taglamig, taglagas, tagsibol at tag-ulan.[1]
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.

You know the answer is correct when the answer has a good star review such as 5 stars or has a good amount of likes. Everyone has a title by their name, the higher status it is, the more likely their answer would be right.
The ratio (red to blue) of the perimeters of the similar triangles is 12:7
Assuming that the similar triangles are equilateral triangles, then all their sides will be equal.
Perimeter of a triangle = s1 + s2 + s3
For the red triangle;
Perimeter of the red triangle = 12 + 12 + 12
Perimeter of the red triangle = 36
For the blue triangle:
Perimeter of the blue triangle = 7 + 7 + 7
Perimeter of the blue triangle = 21
Taking the ratio of their perimeters;
Ratio of red to blue = 36:21 = 12:7
Hence the ratio (red to blue) of the perimeters of the similar triangles is 12:7
