R is 4 if I'm wrong sorry
Answer:
NO
Step-by-step explanation:
Draw a triangle and label the sides a, b and c. Now we must know the rule you can use for drawing any triangle:
A+B> c
A+C>B
B+C>A
Sub you numbers into the rule:
8+10, is it greater that 19?
No, 8+10=18 and 18<19
This is proof that you can not draw a triangle with the side lengths of 8m, 10m and 19m.
Answer:
-8

Hope this helps, have a great day:)
The given function has no undefined points nor domain constraint. Thus, the domain is:
.
<h3>Domain and Range</h3>
The domain of a function is the set of input values for which the function is real and defined. In the other words, when you define the domain, you are indicating for which values x the function is real and defined. An example, there is a restriction for the domain of fractions. The variable x in the denominator should be different of zero.
While the domain is related to the values of x, the range is related to the possible values of y that the function can have.
In this question, the function
has no undefined points nor domain constraint. Therefore, the domain is:

Answer:
4a2 + 4a + 1 = (2a +1)^2 = (2a + 1)(2a + 1)
4 − 4a + a2 = (2 - a)^2 = (2 − a)(2 − a)
4a2 − 4a + 1 = (2a -1)^2 = (2a − 1)(2a − 1)
4 + 4a + a2 = (2 + a)^2 = (2 + a)(2 + a)
