Answer:
14x + 11
Step-by-step explanation:
note that (f + g)(x) = f(x) + g(x)
f(x) + g(x)
= 4x + 13 + 10x - 2 ← collect like terms
= 14x + 11
<em>Aaron 14 years</em>
<em>Devon 17 years</em>
<em>D = A + 3</em>
<em>D + A = 31</em>
<em>replace D</em>
<em>A + 3 + A = 31</em>
<em>2A = 31 - 3</em>
<em>2A = 28</em>
<em>A = 14 years</em>
<em>D = 17 years</em>
f (-2)=5×-2+4
= -10+4
= -6
f (3)=5×3+4
=15+4
=19
f (5)=5×5+4
25+4
=29
14.6666666667
2•10=20/1/3=6.66666666667+8 is that but you can write it like 14.6 with _ that on top
