Given that f(x) = x2 + 10x + 21 and g(x) = x + 7, find (f•g)(x) and express
sammy [17]

Answer:

<h2>(f.g)x =  {x}^{2}  + 24x + 140</h2>

Step-by-step explanation:

given \\ f(x) = x ^{2}  + 10x + 21 \: and \: g(x) = x + 7

as \: we \: know \: (f.g)x \: is \: same \: as

f(g(x))

so \:

f(x + 7) = ( x + 7) ^{2}  + 10(x + 7) + 21

f(x + 7) =  {x}^{2}  + 14x + 49 + 10x + 70 + 21

f(x + 7) = x^{2}  + 24x + 140

therefore

(f.g)x =  {x}^{2}  + 24x + 140

PLS ESTIMATE/ 67% of 8.7
Studentka2010 [4]
67 percent of 8.7

\frac{67}{100}  \times  \frac{x}{8.7}
100x = 67 \times 8.7

100x = 582.9

Divide by 100 on both sides to isolate the x

x = 5.829
Round up (to the nearest tenth place and whole number)

x = 6
x = 5.8
