3-b) 216²/³ = ∛216² = ∛(6x36)² = 36
3-c) 256⁻¹/⁴ = 1/(256¹/⁴) = 1/(⁴√256) = 1/4
Answer:
C is the correct answer I might get this wrong and if so sorry.
Step-by-step explanation:
Answer:
X = 5
Step-by-step explanation:
Here is what I am picturing (not to scale)
A ----------------B-----------C
We are given the information of AB (which equals 3x + 1), BC (which equals 4x - 5), and AC (which equals 8x - 9).
With reference to the line, AB + BC = AC
So,
3x + 1 + 4x - 5 = 8x - 9
7x - 4 = 8x - 9
5 = x
Y is going to be the number 40
x will equal 90
