To start, we need to distribute
multiply 2x by <em>everything</em> in the parenthesis
2x (5 + 3x) - x
2x × 5 = 10x
2x × 3x = 6x²
now we have...
10x + 6x² - x
<em>simplify </em>
<u>6x² + 9x </u>
the coefficient of x is 9!

Answer:
The probability that a randomly selected woman has red/green color blindness is 0.9914
Step-by-step explanation:
Given that the proportion of women having red/green color blindness is 0.86%
Represent that with p

Convert proportion from percentage to decimal;


In probability; opposite probabilities add up to 1;
Let the probability that a woman selected have red/green color blindness be represented with q;

Subtract p from both sides


Substitute 0.0086 for p


<em>Hence, the probability that a randomly selected woman has red/green color blindness is 0.9914</em>
Answer:
x = 1 or x = 
Step-by-step explanation:
The expression inside the absolute value function can be positive or negative
That is 3x - 7 = ± 4
There are 2 equations to solve
(1)
3x - 7 = 4 ( add 7 to both sides )
3x = 11 ( divide both sides by 3 )
x = 
(2)
3x - 7 = - 4 ( add 7 to both sides )
3x = 3 ( divide both sides by 3 )
x = 1
