Pembahasan:

This question tests your understanding of algebraic manipulation and problem-solving skills. First, we need to find a way to relate the given equations to the expression abc. Remember the identity:

(a + b + c)^2 = a^2 + b^2 + c^2 + 2(ab + bc + ca)

We can use this identity to find the value of ab + bc + ca. Substituting the given values, we get:

6^2 = 14 + 2(ab + bc + ca)
36 = 14 + 2(ab + bc + ca)
22 = 2(ab + bc + ca)
ab + bc + ca = 11

Next, we need to find another identity that relates a^3 + b^3 + c^3 to abc. Remember the identity:

a^3 + b^3 + c^3 - 3abc = (a + b + c)(a^2 + b^2 + c^2 - ab - bc - ca)

Substituting the given values and the value of ab + bc + ca we found earlier, we get:

36 - 3abc = 6(14 - 11)
36 - 3abc = 6(3)
36 - 3abc = 18
3abc = 18
abc = 6

So, the value of abc is 6. See, it wasn't that hard, was it? The key is to remember the relevant identities and how to apply them.

Pembahasan:

This is a geometry question that requires you to apply the Pythagorean theorem and the formula for the area of a triangle. First, we need to find the length of the other leg of the right triangle. Let the legs be a and b, and the hypotenuse be c. We are given that c = 25 cm and one leg, say a, is 7 cm. By the Pythagorean theorem:

a^2 + b^2 = c^2
7^2 + b^2 = 25^2
49 + b^2 = 625
b^2 = 576
b = 24

So, the length of the other leg is 24 cm. Now, we can find the area of the triangle using the formula:

Area = (1/2) * base * height
Area = (1/2) * 7 * 24
Area = 84

Therefore, the area of the triangle is 84 cm². See, guys, this question combines the Pythagorean theorem with the area of a triangle formula. It shows how important it is to have a solid understanding of basic geometric concepts.

Jawaban: 84 cm²

This example highlights the importance of knowing fundamental geometric theorems and formulas. The Pythagorean theorem is a cornerstone of geometry, and understanding how to apply it in various contexts is essential. Similarly, knowing the formula for the area of a triangle is crucial. Practice applying these concepts to different types of geometric problems, such as finding the perimeter, volume, or surface area of other shapes. The more you practice, the better you'll become at visualizing geometric figures and identifying the relevant formulas to use. Also, try to draw diagrams to help you visualize the problem; this can often make it easier to understand the relationships between the different elements of the figure. Remember, guys, geometry is all about visualizing and understanding spatial relationships.

Berapakah nilai dari:

1 + 2 + 3 + ... + 99 + 100

Pembahasan:

This question tests your understanding of arithmetic series. Instead of adding the numbers one by one, we can use the formula for the sum of an arithmetic series. The sum of the first n natural numbers is given by:

S = n(n + 1) / 2

In this case, n = 100, so:

S = 100(100 + 1) / 2
S = 100(101) / 2
S = 5050

Therefore, the sum of the numbers from 1 to 100 is 5050. Isn't that much easier than adding them one by one? This question demonstrates the power of knowing formulas and how they can simplify calculations.

Jawaban: 5050

This example showcases the usefulness of arithmetic series formulas in solving problems quickly and efficiently. Understanding the properties of arithmetic series and other sequences and series is an important part of mathematics. Instead of memorizing the formula, try to understand where it comes from. For instance, you can visualize the sum as pairing the first and last numbers (1 + 100), the second and second-to-last numbers (2 + 99), and so on. Each pair sums to 101, and there are 50 such pairs, so the total sum is 50 * 101 = 5050. Understanding the logic behind the formula will help you remember it better and apply it more confidently. Also, practice identifying different types of sequences and series, such as geometric series and harmonic series, and learn their corresponding formulas. Mastering these concepts will greatly enhance your problem-solving abilities.
