Answer:
(2 z + 3) (4 z^2 - 6 z + 9)
Step-by-step explanation:
8z3 + 27
a = 2z
b = 3
a^2 = (2z)^2 = 2z^2
ab = (2z)*3 =6z
b^2 = 3^2 =9
a3 + b3 = (a + b)(a2 – ab + b2)
8z^2 +27 = (2z+3) (4z^2 -6z +9)
The answer is the third one
Rounding it to the tens place so your answer for 12mm is going to be 10
when we have an exponent means that the base is multiplied times the number that is as the exponent, since there is no parentheses the exponent only affects the 4
