It depends on the side lengths, but the sum of all the angles is 360°
If degree of variable is one then eq. is linear
so given is linear.
Answer:
(the second option)
Step-by-step explanation:
Hope this helps!
For this case what we have to take into account is the following variable:
x = represent the unknown number
We now write the following inequality:
"four times the sum of number and 15 is at least 20"
4 (x + 15)> = 20
We clear the value of x:
(x + 15)> = 20/4
(x + 15)> = 5
x> = 5 - 15
x> = - 10
The solution set is:
[-10, inf)
Answer:
all possible values for X are:
[-10, inf)
