Answer:
1) True
2) False
3) False
4) True
Step-by-step explanation:
1) True
Anything over 100% is larger than the original.
2) False
Since it is 225% bigger, you multiply 4 by 2.25.
4 x 2.25 = 9
3) False
If it is 225% larger, it means that it is 2.25 times larger
4) True
Vertical angles are congruent due to the fact that they intersect. If they did not, they would in fact be parallel. (last section)
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 ....
