(xyz²)⁴
(x)⁴(y)⁴(z²)⁴
x⁴y⁴z⁸
The correct answer would be: 50-(3x+4y+25) because the sum of what's in parethese is what it cost Sianna to buy all of it.
Answer:
My answer may not be accurate, but try (-4, 2)
I recommend using Khan Academy if you still don't understand the concept. (no shame btw)

Here is a thorough explanation.
Interval notation is a way of writing subsets of the real number line . A closed interval is one that includes its endpoints: for example, the set {x | −3≤x≤1} . To write this interval in interval notation, we use closed brackets [ ]: [−3,1]
Answer:
-15 < 20
Step-by-step explanation:
5(w - 3) < 5w + 20
Distribute;
5w - 15 < 5w + 20
Subtract 5w from both sides;
-15 < 20
X= -3
2/3x-10=12
Step 1: Add 10 to both sides.
2/3x=-2
Step 2: Multiply both sides by 3/2.
x= -3
