Answer:
<h2>
7</h2>
HCF of 49 and 84 is 7.
Step-by-step explanation:
mark me brainliest
(3x^3 + 4x²) + (3x^3 – 4x^2 – 9x) =
We have to combine like terms, terms that have x raised to the same power:
First, eliminate the parenthesis:
3x^3 + 4x² + 3x^3 – 4x^2 – 9x =
We have 2 terms raised to the second power (4x^2 and -4 x^2) simply add and subtract.
3x^3+3x^3+4x^2-4x^2-9x
6x^3-9x
Each square is 2.2*2.2= 4.84 sqin
6 squares: 4.84*6= 29.04
hope this helps
