Hi! So to solve for these, all you have to do is keep PEDMAS in mind. For example, for 2x^3 (Just a fancy way of writing "to the third power") first plug in 3: 2(3)^3 and take it to the third power because E (exponent) comes before M (multiplication) in PEDMAS. You should get 2(27) which then equals 54. Hope this helps:)

Arturiano [62]

Answer:

0.7575757575757576 or 0.76

Step-by-step explanation:

5/6 = 0.8<u>33</u>

10/11 = 0.9090909090909091

0.8<u>33</u> x 0.9090909090909091 = 0.7575757575757576

Answer:

a = 10; a = 2

Step-by-step explanation:

Step 1: Use the Pythagorean theorem to solve this equation

1. Orignal eqaution: (a + 2)² + (a - 5)² = (a + 3)²

2. Expand (a + 2)² + (a - 5)² which will give us 2a² - 6a + 29

3. Expand (a + 3)² giving us a² + 6a + 9

4. Simplified equation: 2a² - 6a + 29 = a² + 6a + 9

Step 2: Subtract 9 from both sides

1. 2a² - 6a + 29 - 9 = a² + 6a + 9 - 9

2. Simplify: 2a² - 6a + 20 = a² + 6a

Step 3: Subtract 6a from both sides

1. 2a² - 6a + 20 - 6a = a² + 6a - 6a

2. Simplify: 2a² -12a + 20 = a²

Step 4: Subtract a2 from both sides

1. 2a² - 12a + 20 - a² = a² - a²

2. Simplify: a² - 12a + 20 = 0

Step 5: Use the quadratic formula to solve for a

1. Quadratic formula: a = -b += √b² - 4ac/2a

2. Plug in the correct values: a = -(-12) += √(-12)² + 4(1)(20)/2(1)

3. Simplify the numerator and denominator: 12 += 8/2

4. Final equation: a = 12 - 8/2 or a = 12 + 8/2

5. Hence, the answer is 10 or 2
