Answer:

LCD of 7 and 5 is 35

Step-by-step explanation:

In many cases, you can find the lowest common denominator by simply multiplying the two numbers together. This method works in your example.

7 x 5 = 35

The two fractions would become 15/35 and 28/35

There will be times when this will not get you straight to the answer, eg find the lowest common denominator of 8 and 12. For this you need to list some multiples of the numbers until you get a number which appears in both lists:

8: 8, 16, 24

12: 12, 24

So, the lowest common denominator of 8 and 12 is 24.

an actor gains 20pounds for a part and then losses 15 pounds during the filming of the movie to go along with the story.who do y
guajiro [1.7K]
Let the actor's initial weight be 'x'

He is then gaining 20 pounds. The clue is in the word 'gaining' as it means 'increasing' or in Mathematics can be related as 'plus'

The expression is: x+20

He then loses 15 pounds. The clue is in the word 'losses' as it means 15 pounds is to be subtracted from the last value

Last value is x + 20
The weight now is x + 20 - 15 = x + 5

What is the product of -2x^3+x-5 and x^3-3x-4 ?
murzikaleks [220]
To find the product of <span>-2x^3+x-5 and x^3-3x-4, we need to multiply each term in the first polynomial by the second polynomial. (So, x^3 - 3x - 4) times ....
-2x^3 = -2x^6 + 6x^4 + 8x^3
x = x^4 - 3x^2 - 4x
-5 = -5x^3 + 15x + 20
If we add all these together, we get (-2x^6 + 7x^4 + 3x^3 - 3x^2 + 11x + 20)</span>
