حضور اکرم صلی اللہ علیہ وسلم نے اس معاہدے کو پسند فرمایا کیونکہ اس میں انصاف اور مظلوموں کی مدد کا وعدہ کیا گیا تھا۔

Explanation

Let x be the number of years in the future. Then:

Father’s age = 41 + x, Son’s age = 9 + x

Set up the equation: 41 + x = 3(9 + x)

→ 41 + x = 27 + 3x → 14 = 2x → x = 7 years.

Explanation

This is a statement of the Triangle Inequality Theorem, which states that the sum of any two sides of a triangle must be greater than the third side.

It ensures the sides form a valid triangle.

Explanation

"Whatever" is used to refer to anything that the subject (you) cooks.

"Whichever" is used when selecting from a limited set of options.

"What" is a question word.

Explanation

A meteorite is a small solid rock that survives its passage through the Earth's atmosphere and lands on the surface.

Explanation

A teacher should be a researcher to stay updated with new knowledge and teaching methods.

A teacher should be a psychologist to understand students' behavior and learning needs effectively.

Explanation

Explanation

The points form a scalene triangle:

Calculate the distances AB, BC, and AC. If all sides are unequal, it's a scalene triangle.

AB = √((1 - (-4))² + (4 - (-2))²) = √(5² + 6²) = √61

BC = √((6 - 1)² + (11 - 4)²) = √(5² + 7²) = √74

AC = √((6 - (-4))² + (11 - (-2))²) = √(10² + 13²) = √269

All sides are unequal (√61 ≠ √74 ≠ √269), so the points form a scalene triangle.

Explanation

The pith is the central part of the stem, mainly used for storage of nutrients and water.

It is surrounded by vascular tissues that transport water and nutrients throughout the plant.

Explanation

Problem-Based Learning (PBL) presents students with real-world, open-ended problems without a clear solution.

It encourages group collaboration, critical thinking, and self-directed learning to find solutions.
