Answer:
17.4 cm²
Step-by-step explanation:
base = 3x2.6x0.5 = 3.9 cm²
3 sides = 3(3)(3)(0.5) = 13.5 cm²
13.5 + 3.9 = 17.4 cm²
Answer:
The answer is 12a^3+2a²+23a+18 ....
Step-by-step explanation:
The given terms are:
(3a + 2)(4a² - 2a + 9)
Now multiply each value of second bracket with the first bracket:
=4a²(3a+2) -2a(3a+2)+9(3a+2)
=12a^3+8a²-6a²-4a+27a+18
Solve the like terms:
=12a^3+2a²+23a+18
Therefore the answer is 12a^3+2a²+23a+18 ....
