Answer:
The answer is 2.89 in 2dp
3 cube is 27
27 minus 6.8 is 20. 2
20. 2 decide by 7 is 2.89
Answer:
Yup
Step-by-step explanation:
91 - 22 = 69
Combine 2a^3+5a-7 and 5a^2-6a+12.
Rewrite this so that the second expression is beneath the first:
2a^3+5a-7
5a^2-6a+12
Combine like terms. The highest order term is 2a^3:
2a^3+0a^2 +5a-7
+5a^2 - 6a+12
----------------------------
2a^3 + 5a^2 - a + 5 (answer)
Note how these terms are in descending order by power of a.
