Add two like terms: 16x+(-9x)=7x
Add 15 to both sides: 7x=28
Divide 7 on both sides: x=4
Answer: Hello mate!
The partition of a set is defined as a partition of the set into a nonempty subset, where the set itself is a subset of himself, then the set is a partition of himself.
a) in this we have a set of two objects; A = (1,2) the partitions of this set are: (∅), (1), (2) and (1,2). Where (∅) is the null set.
b) Now we have a set of three objects; B = (a,b,c) the partitions of this set are: (∅), (a), (b), (c), (a,b), (a,c), (b,c), (a,b,c)
Multiply it out
x^2 + 4x -8x -32
Combine like terms
x^2 -4x - 32
X^2-3x-10. You solve it by foiling. I attached a photo explaining how to do it.
Answer:
0 ≤ x ≤ 5
Step-by-step explanation:
I used the Desmos calculator
