7 multiplied by 6 equals 42, making it the correct answer. Multiplication basics are essential for building a strong foundation in math.

By dividing both the numerator and denominator by 4, the fraction 4/8 simplifies to 1/2. This basic reduction is key in fraction operations.

The formula for the perimeter of a rectangle is 2 Ã - (length + width). Plugging in the values gives 2 Ã - (5 + 3) = 16.

The theme of a literary work refers to its central message or underlying idea. This concept is fundamental in understanding the overall meaning of a story.

The past tense of 'run' is 'ran', which is an irregular verb form in English. Recognizing irregular verbs is important for proper grammar usage.

Subtracting 3 from both sides yields 2x = 8, and dividing both sides by 2 gives x = 4. This linear equation reinforces basic algebraic skills.

The sentence emphasizes perseverance by showing a character's refusal to give up despite challenges. The tone of hope and determination is clearly communicated.

First, compute 4 + 5 to get 9, then multiply by 3 to obtain 27, and finally subtract 2 to arrive at 25. This question tests proper use of the order of operations.

Using the slope formula (y2 - y1) / (x2 - x1) gives (11 - 3) / (6 - 2) = 8/4 = 2. This reinforces concepts in coordinate geometry.

Foreshadowing is used by authors to hint at future events, thereby preparing the reader for what is to come. Recognizing this device is important for literary analysis.

Calculating 20% of 150 involves multiplying 150 by 0.20, which results in 30. This percentage calculation is a common application in math problems.

Multiplying both sides of the equation by 3 isolates x, which gives x = 15. This demonstrates the use of inverse operations in solving equations.

Imagery involves using descriptive language to create a sensory experience for the reader. The vivid depiction of a sunset over a calm sea effectively evokes visual imagery.

Increasing a number by 25% multiplies it by 1.25, and then decreasing the new value by 20% multiplies it by 0.8. Multiplying 1.25 by 0.8 returns the original number, leaving it unchanged.

Context clues are hints within the surrounding text that help readers infer the meaning of unknown words. This strategy enhances comprehension and vocabulary skills.

By expressing y from the second equation as x - 1 and substituting into the first equation, you obtain 2x + (x - 1) = 10, which simplifies to x = 11/3 and y = 8/3. This problem reinforces the substitution method for solving systems of equations.

Let the width be w; then the length is 2w. The perimeter is calculated as 2(w + 2w) = 6w. Setting 6w equal to 36 gives w = 6 and the length as 12.

Symbolism involves using concrete objects or events to stand for abstract ideas or themes, thereby adding depth to the narrative. This technique often allows readers to uncover deeper meanings beyond the literal text.

Substitute x = 3 into the function: f(3) = 2(3²) - 3(3) + 1 = 18 - 9 + 1, which equals 10. This problem tests evaluating a quadratic function using substitution.

The sentence attributes the human ability to 'witness' to an inanimate object, which is a clear example of personification. Recognizing such literary devices is crucial for in-depth textual analysis.
