Answer:
Hello!
To answer these, you can use prime factorization! Here is the first one:
1) 16x² and 8
Well we know the GCF will not have any "x" since only one of the numbers do. So, here is the prime factorization for each, excluding the "x", and I have also bolded the common numbers between the two:
16 8
2 · 8 2 · 4
2 · 4 2 · 2
2 · 2
Finally, multiply the common numbers (only once for each common number): 2 x 2 x 2= 8 is your GCF!!!
Hope this helps! :)
Answer:
a) 28
Step-by-step explanation:
Corrected Question
Determine the values of a, b and c that make each equation true.

Answer:
a=-5, b=28 and c=-11
Step-by-step explanation:
To solve for a,b and c, we apply the following laws of indices

Therefore

To solve for b

To solve for c

Its maybe Find the area of the shaded portion sorry it’s wrong I tried my best
Answer:
The correct option would be x^3
Step-by-step explanation:
The amount that you can take away from both of the numbers would be the correct answer.
The answer would basically be the lowest number that is there
Say you have x^7 and x^4
The GCF would be x^4
