Answer:
1. G
2. J
3. E
4. A
5. F
6. C
7. I
8. B
9. H
10. D
Step-by-step explanation:
1. (a+b)(x)
= x+2 + 5x -3
= 6x - 1
2. (a•b)(x)
= (x+2)(5x-3)
= 5x²-3x+10x-6
= 5x²+7x-6
3. √(x+2)+5
=√x+7
4. x+5/x-7 ÷ 3/x-7
x+5/x-7 × x-7/3
=3/x+5
5. x+5/x-7 - 3/x-7
x+5-3/x-7
=x+2/x-7
6. 6x-1
6(-1)-1
-6-1
= -7
7. 5x²+7x-6
5(0)+7(0)-6
0+ 0-6
= -6
8. √x+7
√2+7
√9
= 3 +/-
9. 3/x+5
3/(-2) +5
3/3
= 1
10. x+2/x-7
2+2/2-7
4/-5
= -4/5
