Answer:
1. 1
2. -4
3. 0
4. 0
5. 2
Step-by-step explanation:
a= 1 b= -1 c= 2
1. 3ab+4
3(1)(-1)+4
-3+4
= 1
2. 5b+3a- 5(-1)+3(1)-2
-5+3-2
-2-2
= -4
3. 6b+3c
6(-1)+3(2)
-6+6
=0
4. 4a-2c
4(1)-2(2)
4-4
=0
5.
[tex] \frac{5c + 2b}{4a} [/tex]
[tex] \frac{5(2) + 2( - 1)}{4(1)} [/tex]
[tex] \frac{10 - 2}{4} [/tex]
[tex] \frac{8}{4} = 2[/tex]
