Answer:
6
Step-by-step explanation:
I assume you mean GCF, greatest common factor.
First, write the prime factorizations for each:
18 = 2¹ × 3²
24 = 2³ × 3¹
Next, find what they have in common. Both have a factor of 2¹ and 3¹.
GCF = 2¹ × 3¹
GCF = 6
The greatest common factor is 6.
Make each into improper fraction
2 x 8 + 5. = 21 / 8
3(10) + 2 = 32/3
21/8(32/3) = ((21x32)/(8x3) reduce by 3/3
(7x32)/(8) reduce by 8/8
7x4 = 28
Step-by-step explanation:
f(x)=-x²+8x
By replacing x with -7, we get
f(-7)=-(-7)²+8×(-7)
=-49-56
=-105
