Hi there!
We are given the equation w² + 7w + 12 = 0, and we are told to solve it. Well, we can first take all the factors of 12 -
1 12
2 6
3 4
Now, take the sum of each factor pair -
1, 12 = 13
2, 6 = 8
3, 4 = 7
Find which factor pair adds up to 7, and we can see that 3 and 4 add up to seven, while also having a product of 12. Therefore, since the whole equation has addition signs, we can factor the equation w² + 7w + 12 into (w + 3)(w + 4) = 0. Next, using the Zero Product Property, we can set each term to zero.
w + 3 = 0
w = -3
w + 4 = 0
w = -4
Therefore, the solution to the equation w² + 7w + 12 = 0 is w = -3, -4. Hope this helped and have a great day!
Hi there!
Since the digit 5 is in the thousandths place, the answer is 0.005.
Hope this helps!

For this case we have two televisions, one generic version and one brand. We know that the generic version represents
the size of the brand. We must define two variables that represent the dimensions of the brand TV, so we have:
Dimensions of the generic TV:

So:


By clearing the variables we have:

Thus, the dimensions of the brand TV are 18 inches by 36 inches
Answer:
The dimensions of the brand TV are 18 inches by 36 inches
