The intersection of sets P and Q can be found by identifying the elements that are common to both sets. In this case, the elements 3, 5, and 7 are present in both sets P and Q. Therefore, the correct answer is B. {3, 5, 7}.

Tasya answered 14 questions correctly, which means she will receive a score of 5 for each correct answer. She answered 3 questions incorrectly, which means she will receive a score of -1 for each incorrect answer. The remaining questions that she did not answer will receive a score of 0. To calculate her total score, we can multiply the number of correct answers by 5, the number of incorrect answers by -1, and add the result to the number of unanswered questions multiplied by 0. Therefore, Tasya's total score is 14 * 5 + 3 * (-1) + 3 * 0 = 70 - 3 + 0 = 67.

In this sentence, the word "soup" indicates that we are talking about food. Oil and paint are not typically used in food preparation, so they can be eliminated as options. Butter is a possibility, but it is not as common to add butter to soup as it is to add salt. Salt is a common ingredient in soup and is used to enhance the flavor. Therefore, the most likely answer is c. Salt.

In this conversation, Romy is meeting Vivian for the first time. The appropriate response in this situation is to use a formal greeting, which is "How do you do." This phrase is commonly used as a polite way to greet someone when you are meeting them for the first time. It shows respect and acknowledges the introduction made by Ferly. The other options, such as "How are you" or "What is up," are more casual and would not be suitable in this formal introduction.

The given equation is 30 + 6x = 12. To solve for x, we need to isolate the variable on one side of the equation. First, we subtract 30 from both sides to get 6x = -18. Then, we divide both sides by 6 to get x = -3. Therefore, the correct answer is B. x = -3.

The inequality x + 4 ≤ 9 can be solved by subtracting 4 from both sides of the inequality. This gives us x ≤ 5. Therefore, the values of x that satisfy the inequality are 0, 1, 2, 3, 4, and 5.

Based on the given information, Umur Haryanti is currently five years older than Hadi. In six years, the sum of their ages will be 51. Therefore, we can calculate Hadi's age now by subtracting 6 from 51 and then dividing the result by 2 (since Haryanti is five years older). This calculation gives us Hadi's age as 22.

The complement of set A is the set of elements in the universal set S that are not in A. In this case, the universal set S is {1, 2, 3, 4, 5, 6} and set A is {1, 2, 3, 5}. Therefore, the complement of A would be the elements in S that are not in A, which are {4, 6}.

The initial temperature in the freezer is 21 degrees Celsius and it decreases to -6 degrees Celsius after the cooling device is turned on. To find the temperature drop, we subtract the final temperature from the initial temperature: 21 - (-6) = 21 + 6 = 27. Therefore, the temperature drop is 27 degrees Celsius.

Faiza is a philatelist, which means she collects stamps. Philatelists are individuals who have a keen interest in collecting and studying stamps. They often collect stamps from different countries, periods, or themes, and may even study the history and significance of each stamp. Therefore, it is logical to conclude that Faiza's interest lies in collecting stamps rather than envelopes, letters, or coins.

The expression can be simplified using the order of operations. First, we perform the multiplication: -12 x (-3) = 36. Then, we perform the division: 42 ÷ 7 = 6. Finally, we perform the addition and subtraction: 14 + 6 - 36 = -16. Therefore, the correct answer is D. 56.

The question is asking for the correct order of steps to follow in order to study at home effectively. The word "please" in the question suggests that these steps should be done in a polite and respectful manner. Looking at the options, option B, 3-1-4-2-5, seems to be the most logical order. Step 3, "hard - everyday," suggests that studying should be done diligently and consistently. Step 1, "study," is the first step in the process. Step 4, "at home," specifies the location where the studying should take place. Step 2, "please," emphasizes the importance of being polite and respectful while studying. Step 5, "everyday," indicates that studying should be done on a daily basis.

The given expression is a multiplication of two binomials. To find the product, we can use the distributive property. Multiplying the first terms of each binomial, we get -2x * 3 = -6x. Multiplying the outer terms, we get -2x * 5x = -10x^2. Multiplying the inner terms, we get 5 * 3 = 15. Multiplying the last terms, we get 5 * 5x = 25x. Combining all these terms, we get -10x^2 + 19x + 15. Therefore, the correct answer is C. -10 x pangkat 2 + 19x + 15.

The given expression can be simplified by combining like terms. Combining the "a" terms, we have -5a + 3a = -2a. Combining the "b" terms, we have -6b + 2b = -4b. Therefore, the simplified form of the expression is -2a - 4b, which matches option D.

The correct answer is "a. It" because the pronoun "it" is used to refer to a singular noun, in this case, the dog. Since James has a dog, he takes "it" for a walk every day.

The given expressions are all ways of introducing oneself to others except for option d. "I would like to introduce you to my friend, Franda."

It implies that the speaker wants to introduce the listener to their friend, Franda.

The question states that the length of the rectangle is (3x + 2) cm and the width is (2x - 1) cm. The perimeter of a rectangle is given by the formula P = 2(l + w), where P is the perimeter, l is the length, and w is the width. Given that the perimeter is 32 cm, we can set up the equation 32 = 2((3x + 2) + (2x - 1)). Simplifying this equation gives us 32 = 10x + 2. Solving for x, we find x = 3. Substituting this value back into the width equation, we find the width is 5 cm. Therefore, the correct answer is D. 5 cm.

The correct answer is C. 1, 3, and 4. This is because statement 1, "x + 15 = 10," is an equation and not an open sentence. Statement 2, "5a + 9a = 14a," is also an equation and not an open sentence. However, statement 3, "3y - 7 = 2y + 14," is an open sentence as it contains variables and an inequality. Statement 4, "g adalah bilangan ganjil," is also an open sentence as it contains a variable and a condition (odd number). Therefore, the correct answer is C. 1, 3, and 4.
