Rewrite 4/7 and 6/11 so that they have a common denominator.

Answers

For this, you have to calculate LCM of denominators i.e., 7 and 11 that will be 77

Now, 77/7 = 11, so 4*11=44 & 77/11 = 7, so 6*7=42

44/77 and 42/77 is the answer

Final answer:

To get a common denominator for the fractions 4/7 and 6/11, we find the least common multiple of 7 and 11, which is 77. The fraction 4/7 becomes 44/77 when both numerator and denominator are multiplied by 11, and the fraction 6/11 becomes 42/77 when both are multiplied by 7.

Explanation:

In simple terms, a common denominator is found by identifying the least common multiple (LCM) of the denominators you are working with.  In this instance, we are facing two fractions: 4/7 and 6/11. The LCM of 7 and 11 is 77, because 7 and 11 are both prime numbers and prime numbers only have one common multiple - their product.

So, you can rewrite these fractions as follows:

  1. For 4/7, you multiply both the numerator (the top number) and the denominator (the bottom number) by 11. This gives you 44/77.
  2. For 6/11, you multiply both the numerator and the denominator by 7. This gives you 42/77.

What is the product of -9 and -15?
135
-135
-24
24

Answers

-9 * (-15) = 135
it's positive 135 because when you have negative time a negative it's always positive.

Answer:

Please mark me brainliest and I hope this helped!

135

Step-by-step explanation:

The product of something is what the outcome is when you multiply the numbers together. Since 9 and 15 are both negatives, they cancel each other out and become positives. Then we just multiply 9 and 15. That gives us 135.

BEST ANSWER GETS A METAL!!!!Which pair of complex numbers has a real-number product?

(1 + 3i)(6i)
(1 + 3i)(2 – 3i)
(1 + 3i)(1 – 3i)
(1 + 3i)(3i)

Answers

we will proceed to verify each case to determine the solution

remember that

i^(2) =-1

case A)(1 + 3i)(6i)

applying distributive property

(1 + 3i)(6i)=1*6i+3i*6i \n=6i+18i^(2)\n=6i+18*(-1)\n=6i-18

-18+6i ------> is not a real number

therefore

the case A) is not a real number product

case B)(1 + 3i)(2-3i)

applying distributive property

(1 + 3i)(2-3i)=1*2+1*(-3i)+3i*(2)+3i*(-3i)\n=2-3i+6i-9i^(2)\n=2+3i-9*(-1) \n=11+3i

11+3i ------> is not a real number

therefore

the case B) is not a real number product  

case C)(1 + 3i)(1-3i)

applying difference of square

(1 + 3i)(1-3i)=(1)^(2)-(3i)^(2)\n=1-9i^(2)\n=1-9*(-1) \n=10

10 ------> is a real number

therefore

the case C) is  a real number product  

case D)(1 + 3i)(3i)

applying distributive property

(1 + 3i)(3i)=1*3i+3i*3i \n=3i+9i^(2)\n=3i+9*(-1) \n=3i-9

-9+3i ------> is not a real number

therefore

the case D) is not a real number product

the answer is

(1 + 3i)(1-3i)

     

The answer is (1 + 3i)(1 – 3i).
