For this case we have the following equation:
12x2-5x-2 = 0
Using the resolver we have:
x = (- b +/- root (b ^ 2 - 4 * a * c)) / (2 * a)
Substituting values we have:
x = (- (- 5) +/- root ((- 5) ^ 2 - 4 * 12 * (- 2))) / (2 * 12)
Rewriting:
x = (5 +/- root (25 +96))) / (2 * 12)
x = (5 +/- root (121))) / (2 * 12)
x = (5 +/- 11) / (2 * 12)
Answer:
One root is positive and another is negative.
Answer:
The surface area of the prism is 72 square units.
Step-by-step explanation:
In order to calculate the surface area of the prism we must calculate the area of each face of the prism. To better visualize it we can look at the picture below. We must calculate the area of every face in the picture, so we have:
surface area = 2*[(1/2)*3*4] + 3*5 + 4*5 + 5*5
surface area = 12 + 15 + 20 + 25
surface area = 72 square units
Answer:
213
Step-by-step explanation:
1. Set up an equation (as you have done there)
2. divide the first digit, so in this case you want to divide 34 / 7 which doesn't work so your gonna add another number 72 and how many times can 34 go into 72 that will be twice so 34 x 2 is 68, and you put the 2 at the top where the line is over 2
3. and then you subtract 72 and 68 and then you get 4.
4. after that you start the process again but doing it by just adding another number so in this case you would 724 at the next step. you stop when you have run out of numbers to add
