The answer to ur question is d: 6x6x6x6
Answer:
D. last option
Step-by-step explanation:
distribute the exponents outside of parentheses to terms in side to get
x^10 y^20 z^5 on top
and x^2 y^2
then you can subtract the exponents of like terms from numerator and denominator to get
x^8 y^18 z^5
So we are given the equation
y = 79.31(1.48)ˣ
Whereas the x represents the number of days <--- what you need to know
y is the final number you are going to get, does not matter for now
You are trying to find the number of bacteria on Day 8
Put 8 into x
PEMDAS

1.48⁸ = 23.019
79.31 * 23.019 = 1825.667
Your answer would be A.
Hi there!
• f(x) = 3x + 1
• g(x) = x² - 6
Then,
According to th' question :-
(f - g)(x) = f(x) - g(x)
= 3x + 1 - (x² - 6)
= 3x + 1 - x² + 6
= -x² + 3x + 7
Hence,
Option 2ⁿᵈ : -x² + 3x + 7 is Correct.
~ Hope it helps!
