(11 + 21) - ( 3 - 100 )
= 32 + 97
= 129

or (11+21)-(3+100)
= 32 - 103
= - 71

I have no idea about your topic but hope it's right! Good luck

Maria has added 2 liters of pure water to 8 liters of a 48% sugar syrup. What is the concentration of the resulting solution?

amm1812

We know that
2 liters of pure water = 0 % of sugar
8 liters of syrup = 48% of sugar

Water = (2 liters x 0%) = 0 total sugar liters
Syrup = (8 liters x 48%) = 3.84 total sugar liters
Total liter mix =8+2-----> 10 liters

Total liters of sugar = 0 + 3.84 = 3.84
if 10 liters-----------> 100%
3.84 liters--------> x
X=3.84*100/10-----> x=38.4%

the answer is
38.4%

Factor the expression completely.

densk [106]

Answer:

$\fbox{\begin{minipage}{13em}Option D: 2(3x + 4)(3x - 4)\end{minipage}}$

Step-by-step explanation:

$A = 18x^{2} - 32\\$

Find the sharing components:

<=> $A=2*9*x^{2} - 2*16$

Apply the inverse of associative property:

<=> $A = 2(9x^{2} - 16)$

Identify two square components inside the parenthesis:

<=> $A = 2((3x)^{2} - 4^{2} )$

Factorize:

<=> $A = 2(3x + 4)(3x - 4)$

=> Option D is correct

Hope this helps!

:)
