Answer:

f(2) = 8, f(8) = 80

Step-by-step explanation:

$f(x)=x(x+2)$

$f(2)=2(2+2)=2(4)=8\\f(8)=8(8+2)=8(10)=80$

ASHA 777 [7]

Answer:

$\[x$

Step-by-step explanation:

Given inequality is $\[-6(4-x)$

Simplifying the inequality by rearranging the terms:

$\[-24+6x$

=> $\[10x$

=> $\[x$

So the given inequality can be simply expressed as $\[x$

Hence x can take all values in the domain which are less than 2.

Liula [17]

Answer:

$g = 11$

Step-by-step explanation:

$26 = 7(g - 9) + 12 \\ first \: you \: need \: to \: distribute \\ \\ 26 = 7g - 63 + 12 \\ add \: - 63 \: to \: 12 \\ \\ 26 = 7g - 51 \\ subtract \: 26 \: from \: both \: sides \\ \\ - 7g = - 77 \\ divide \: both \: sides \: by \: - 7 \\ \\ g = 11$
