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)

If LB = 6 and LN = 2x + 5 , what is x? Show your work.

olga nikolaevna [1]

Answer:

x=3.5

Step-by-step explanation:

MN is divided in half because of MO. BN would equal 6, too. In all, LN should equal 12. So, your equation would be:

2x+5=12

Solve this equation:

2x=12-5

2x=7

x=3.5
