Answer:
- D
- B
Step-by-step explanation:
You may find this easier if you distribute the minus sign first.
<h3>1)</h3>
2a^2 -3ab +5b^2 -a^2 +2ab -3b^2
= (2 -1)a^2 +(-3+2)ab +(5 -3)b^2
= a^2 -ab +2b^2 . . . . . matches choice D

<h3>2)</h3>
6x -3 -2x +2
= (6 -2)x +(-3 +2)
= 4x -1 . . . . . matches choice B
4x+x-2x>4-1-6
5x-2x>4-7
3x>-3
x>-1
(-1, positive infinity]
sadly my phone doesn't have an infinity sign.
it would look like the picture.
34/32 can also be written as 1.0625 or 1 & 1/16.
