Answer:

= 10x² + 9x³

Step-by-step explanation:

I'm assuming you mean question 19

3x² + 5x³ + 7x² + 4x³ (rearrange to group like terms)

=3x² + 7x² + 5x³ + 4x³ (factor out common powers)

= (3+7)x² + (5+4)x³

= 10x² + 9x³

Answer:

3/70

Step-by-step explanation:

change 1/10 and 1/7 so the denominator (bottom number) is the same. 1/10= 7/70 and 1/7= 10/70 so you need 3/70 to make the two numbers equal.
