So you do
distribute
a(b+c)=ab+ac
9(x+5)=9x+9 times 5=9x+45
7(x-3)=7x+7 times -3=7x-21
so now we have
9x+45+7x-21
group like terms
9x+7x+45-21
add
16x+24
simplified is 16x+24
Answer:
D. We can be 95% confident that the proportion of all cell phone users who use text messaging is between 73.1% and 76.9%.

Answer:
The bench cost $325
Step-by-step explanation:
Garden Table + Bench = $742
g + b = $742
Garden Table - Bench = $92
g - b = $92
g = $92 + b
Substitute g into total cost equation
$92 + b + b = $742
$92 + 2b = $742
2b = $650
b = $325
The bench cost $325
Hope this helps :)
