Answer:
18.9
Step-by-step explanation:
4/5 + 3/5 + 3.5 * 5
Well using PEMDAS you would need to do 3.5 x 5 which is 17.5
After that you would to 4/5 + 3/5 which is 7/5 also as 1 2/5
Then you would do 7/5 + 17.5 = 18.9
I might be wrong but that is what I got and I hope it helps you :)
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 ....
