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)
The little squares at corner-B and corner-E were drawn there
to show that those are right angles.
No because the stupidity of you can not calculate
Answer:
Trinomial
Step-by-step explanation:
Because it is broken up in three terms and trinomial means three terms
