* is
Step-by-step explanation:
(7x + 3)(x + 3)
= + 24x + 9
Step-by-step explanation:
use the formula: (a+b)³ = a³+3a²b+3ab²+b³
and place the corresponding values.
I can’t really see the answer choices so I’m going to list all the angles
BFA=40
CFD=50
DFE=40
AFE=140
Answer: B. GCF of 72 and 81 is 9.
C. 72+81 = 9(8+9)
Step-by-step explanation:
The greatest common factor of two or more numbers is the highest number that divides all of them.
Given numbers : 72 and 81
Prime factorization of 72 and 81:
72 = 2 x 2 x 2 x 3 x 3
81= 3 x 3 x 3 x 3
GCF(72,81) = 3x 3 =9
Consider 72+81 = 9 x 8 + 9 x 9 [72= 8 x 9, 81 = 9 x 9]
= 9(8+9)
Hence, B. GCF of 72 and 81 is 9.
C. 72+81 = 9(8+9)
