A.
10
B.
12
C.
24
D.
40
the answer is B.12 because 8*2=16 and 28-16=12
hope i helped
it wood be 13
*2=26 is the anser
1 + {2x - 3(1.8 divided by 0.2)}
a. 2x - 26
b. 2x + 28
c. 3x - 27
d. -7x + 1
The factor of the expression 8r⁶ + 27s¹² can be (2r²+3s⁴)(4r⁴-6r²s⁴+9s⁸) after using the identity a³+b³ = (a+b)(a²-ab+b²).
It is defined as the combination of constants and variables with mathematical operators.
It is given that:
= 8r⁶ + 27s¹²
The above expression can be written as:
8r⁶ + 27s¹² = (2r²)³+(3s⁴)³
After applying the identity:
a³+b³ = (a+b)(a²-ab+b²)
= (2r²+3s⁴)(4r⁴-6r²s⁴+9s⁸)
Thus, the factor of the expression 8r⁶ + 27s¹² can be (2r²+3s⁴)(4r⁴-6r²s⁴+9s⁸) after using the identity a³+b³ = (a+b)(a²-ab+b²).

Answer:
a^3+b^3=(a+b)(a²-ab+b²)
8r^6+27s^12=(2r²)^3+(3s^4)^3=(2r²+3s^4)(4r^4-6r²*s^4+9s^8)
