f(x) = 4x
g(x) =
h(x) =
We want to check if h(x) = g(f(x))
So g(f(x)) =
Simplified;
g(f(x)) =
But h(x) =
Hence g(f(x)) is not equal to h(x)
The perimeter of the square is 80 yards
Answer:
5^3*5^-7 = 1/5^4 b. is true = 625
5^3*5^-7 = 5^-4 c. is true = 625
Step-by-step explanation:
b. Left hand side
Simplify the following:
5^3/5^7
Combine powers. 5^3/5^7 = 5^(3 - 7):
5^(3 - 7)
3 - 7 = -4:
5^(-4)
5^4 = (5^2)^2:
1/(5^2)^2
5^2 = 25:
1/25^2

Answer: 1/625
Right hand side:
Simplify the following:

Answer: 1/625
not going to lie, i was a little confused in the wording for this problem but im guessing the problem is asking for how much books is she reading in one month? ( im sorry if i read that wrong!! )
answer:
1 1/2 books
step-by-step explanation:
all you really need to do is dividing for this whole problem ( and you going to need to add/multiply if you wanted to double check )
first lets divide 12 and 8 by 4
12/4
= 3 books
8/4
= 2 months
now we just need to divide each problem by 2
3/2
= 1.5 or 1 1/2 books
2/2
= 1 month
because we dont need to round 1.5 to the nearest whole number, our answer is 1.5 books in 1 month
hope this helps you! if you need anymore help just ask me :)
