f(a) = 2a + 4

Find g(3)+ f(3)​

Answer 1

Answer:

MARK ME THE BRAINLIEST

g(3)=3³+5×3²

g(3)=3³+5×3²=27+45

g(3)=3³+5×3²=27+45=72

g(3)=3³+5×3²=27+45=72f(3)=2×3+4

g(3)=3³+5×3²=27+45=72f(3)=2×3+4=6+4

g(3)=3³+5×3²=27+45=72f(3)=2×3+4=6+4=10

g(3)=3³+5×3²=27+45=72f(3)=2×3+4=6+4=10So g(3)+f(3)=72+10=82

Answer 2

Answer:

g = ax3=3a

5a x 2 =10 a

F = 2a = 4

a=4/2 = 2

10 ax3=30a

2x3=6

30a +6

30a = 6

a=30/6

A=5

answer is 6
