Use Heron's Formula:
s means semi-perimeter = (50 + 31 + 18) / 2 = 99 / 2 =
49.5
area = sq root [(s * (s-a) * (s-b) * (s-c)]
area = sq root [(49.5 * (s-a) * (s-b) * (s-c)]
This will NOT form a triangle. The longest side (50) is greater than the sum of the other 2 sides.

Answer:The roots are:

and
Explanation:First, we would need to put the equation is standard form which is as follows:
ax² + bx + c = 0
This can be done as follows:
4x² - 12x + 9 - 3 = 0
4x² - 12x + 6 = 0
By comparison, we would find that:
a = 4
b = -12
c = 6
To get the roots, we would substitute in the quadratic formula shown in the attached image.
Doing this, we would find that:
either x =

or x =

Answer:
B. 1.25
Step-by-step explanation:
20/16
Answer:
.493835 to be exact or .5 if your round
Step-by-step explanation:
The two number that when added to the first number, give the second number, and when multiplied, give the second number are:
- a. 4 and 2
- b. 9 and -4
- c. -7 and 3
- d. 5 and 2
- e. -7 and -4
- f. 7 and 9
<h3>What numbers are required?</h3><h3 />
The question requires two numbers that can be added to get the first number and multiplied to get the second.
When 4 and 2 are multiplied, they get 8 and when added they get 6.
When 9 and -4 are added, they get 5 and when multiplied they get 36.
When -7 and 3 are multiplied, they get -21 and when added they get -4.
When 5 and 2 are added, they get 7 and when multiplied they get 10.
When -7 and -4 are multiplied, they get 28 and when added they get -11.
When 7 and 9 are added, they get 16 and when multiplied they get 63.
