Answer:
b
Step-by-step explanation:
This is how I find the GCF.
I find the prime factors.
63/3 = 21
21/3 = 7
7/7 = 1
81/3 = 27
27/3 = 9
9/3 = 3
3/3 = 1
Then I find the common prime factors:
63: 3 x 3 x 7
81: 3 x 3 x 3 x 3
Then I multiply the common prime factors:
3 x 3 = 9
The GCF for 63 and 81 (number 3) is 9.
I bet you can use this method for all the other GCFs! :)
For this one, find the prime factors like before, and if there aren't any besides one, then it's a prime number.
75/3 = 25
25/5 = 5
5/5 = 1
The prime factorization for 75 is 3 x 5 x 5
(I don't know the answer to 7, 8, 9, 10, 11, 12, 25, or 26, sorry!)

It would go closer to the five on the number line. Hope this helps!
Answer:
-54
Step-by-step explanation:
Find f( - 3) × g(4),
for f(x) = x^ - 3
f(-3) = -3^ - 3= -3 × -3 × -3= -27
and g(x) = x^½
g(4) = 4^½ = 2^2^½ = 2 ^1 = 2
f( - 3) × g(4) = -27 ×2 = -54
Hello!
To find the dilation factor you find what figure 1 was multiplied by to get figure 2
Hope this helps!
