Answers and Solutions:

a. (f+g)(5)

=x²–2+3x+1

=x²+3x–1

=(5)²+3(5)–1

=25+15–1

=40–1

➡️(f+g)(5)=39

b. (g–h) (4)

=3x+1–3x–2

➡️(g–h)(4)=–1

c. (f+h)(3)

=x²–2+3x–2

=x²+3x–4

=(3)²+3(3)–2

=9+9–2

=18–2

➡️(f+h)(3)=16

d. (q–v)(1)

=2x+1–10

=2x–9

=2(1)–9

=2–9

➡️(q–v)(1)=–7

e. (p+q)(2)

=x+3+2x+1

=3x+4

=3(2)+4

=6+4

➡️(p+q)(2)= 10

f. (g+q)(3)

=3x+1+2x+1

=5x+2

=5(3)+2

=15+2

➡️(g+q)(3)=17

g. (q–p)(1)

=2x+1–x+3

=x+4

=(1)+4

➡️(q–p)(1)=5

h. (h+p)(2)

=3x–2+x+3

=4x+1

=4(2)+1

=8+1

➡️(h+p)(2)=9

i. (h–v)(5)

=3x–2–10

=3x–12

=3(5)–12

=15–12

➡️(h–v)(5)=3

j. (g+v)(1/3)

=3x+1+10

=3x+11

=3(1/3)+11

=(3/3)+11

=1+11

➡️(g+v)(1/3)=12
