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)

$x = 6$
$x = 5.8$
